Yes it's all an assumption,but he did receive most of his parents abilities/jutsus and surpassed them in it and FTG is based on a fuinjutsu
We saw virtually nothing from his parents though. Minato's participation in fights has been sporadic and short-lived. There isn't too much to go on how he would have handled some of the battle conditions Naruto has had to fight under. He was apparently taught Uzumaki fuinjutsu, but the only things relating to the Uzumaki that we've seen from him are the Eight Trigrams Seal and Shiki Fujin. Most of his fuinjutsu consists of techniques who's origins are unknown (except for the Flying Thunder God technique).
As for Kushina, besides hype as a sealing practitioner and being the jinchuuriki of Kurama, all she's used is a chakra barrier and chains that are capable of restraining 100% Kurama. There's next to nothing that can be assessed about how she would do in a fight except that she was a brawler like Naruto who wasn't very good at ninjutsu.
Kurama admitted to himself that Naruto had surpassed them in terms of the amount of chakra that he could link and transfer to others. I won't deny that Naruto has surpassed them in power (when he still had KCM/BM), but if you're making comparisons based on the specific jutsu that they've both used, Naruto has only really surpassed them in the way of combining his nature transformation with the Rasengan. Minato came to terms with Yin Kurama much more quickly than Naruto did and he was able to use the same jinchuuriki based techniques and modes as efficiently as Naruto without any former training (unless it's confirmed at a later date that he refined his skills to be able to use the bijuu's power inside of the Shinigami's stomach). Their use of summoning jutsu is about the same and Minato can create shadow clones easily (although they're not part of his conventional fighting style).
That sums up the similarities between Naruto and his parents. Of the handful of jutsu that he inherited from them, I would argue that the only ones he's excelled at are the Rasengan, clones, and chakra transference.
i really can't see Naruto son of two masters in fuinjutsus and as one of the two last living members of the Uzumaki clan not having them ,it definitely won't be some kind of an asspull or impossible to happen , that's assuming if Kishi chose not to give Kurama back to Naruto if he goes back than bye bye to all of this :))) .
Is it? I mean his entire clan, including his parents, are dead. Who does he have to learn their jutsu from? Tsunade? Her abilities focus on academic knowledge and precise chakra control. Naruto may have the latter but he's severely lacking in the former. He's not the sort of person who would do book related research. As Naruto himself put it, he learns through experience (muscle memory).
It's true that Naruto has bean shown to work with what he has and expanded on it but he's also shown us that he's always open to learn new jutsus if this wasn't the case than we wouldn't have seen him excited about learning jutsus like the rasengan or the KB, he didn't have them in the begining it's just that at that time he was more focused on how to control the Kuubi's chakra because it was a hindrance to him and it had to be dealt with it as shown in his 3 years traning with Jiraiya and the RS training , if the Kuubi doesn't come back i don't see on what else he can expand on , the only logical thing for him would be to learn a new jutsus/ techniques.
Most jutsu require complicated handseals and memorisation that would not be too effective in the hands of someone like Naruto. It's not suitable for his unique fighting style which emphasises using as few handseals as possible. The only jutsu that I could picture him learning is the Flying Thunder God technique. It doesn't require any handseals and it could be considered a part of the 4th's legacy. It would be better to have it passed down to his son instead of a group of bodyguards.
I would rather see Naruto adjust his fighting style to account for the frog sages' unique jutsu as they fuse with him. Something similar to what Jiraiya displayed against Pain.
About the FTG, you can't compare an instant teleportation with any kind of a speed for the simple reason that the one is instant and bijuu speed isn't no matter how fast you move it still takes time to get to certain destination which's not case with the FTG.
Instantaneous movement is the one thing that FTG has over the shroud. But at the same time, the range of jumping points is limited to wherever you have the mark placed. The shroud doesn't discriminate with location. You can move wherever you want to without restriction and there isn't a potential danger of losing your ability to teleport if your jump point is destroyed.
I belive it's a canon fact that once you put your mark on something it stays forever unless you change your chakra signature or skin (not sure about what he changed)like juubito did. I don't think a what If scenario should be played in this particular case cus there is a lot of possibilities / variations of what can it be done with the FTG if what you said doesn't work for ex: if the kunais are destroyed he can always put a mark on his clones imagine a thousand of them each of them marked, they would be even better than a kunai cus they can actually move on their own it would be overkill , for removing the segment i don't think that would be an god idea if you don't have instant regeneration but i guess anything is better than instant death but i guess eventually the victim will die form blood lost hahaha
Generally, Naruto doesn't summon that many clones unless he's taking a direct human waves tactic approach. He uses clones more conservatively now in an effort to analyse his opponent's tactics. Nevertheless, that strategy wouldn't work against someone with a sturdy enough defence like Sasuke. In the worst case scenario, Sasuke surrounds himself with Amaterasu and equips it as a shield to his Susanoo, deterring Naruto from teleporting close to him. And if it was placed onto Susanoo, what would prevent Sasuke from dispelling the jutsu and removing the mark from play altogether? The pieces with the mark are replaceable for as much chakra as Sasuke can sacrifice.
I can't even begin to imagine how Naruto would handle Perfect Susanoo if a Jinton amplified by Tsunade's chakra couldn't damage it when it was unstabilized.
While he doesn't have the same protection with the shroud he does have the Space -Time Barrier which can wrap any kind of an attack and send it to his opponent so dunno about this. I believe this is to be the case , it's a darn shame really there was so much potential to it but it is what it it is hehehe.
Space-Time Barrier is a technique that requires a complicated set of handseals. Aside from what was already mentioned above, Naruto's sealing stats were always on the lower end of the spectrum, very low in fact at 1.5. That's only half a point higher than Lee's sealing stats. It's one of those things which he's always suffered poorly in.
Regarding Sakura i still haven't lost hope there is a potential for SSM i think ? maybe after the war she will have a training arc where she and Naruto train together Sakura can help him with the seals and Naruto can help her with SM it would be a perfect NS arc 
I don't believe that Sakura will get SSM, but even if she did, it wouldn't be enough to compensate for the gap existing between her and her teammates who have already surpassed their respective teachers and have moved on to parallel Hashirama and Madara.
It would put to rest the tiresome debate about whether she could defeat all of the Rookies (it's disgusting that this is even a debate at all) and possibly Tsunade as well.
Unless she could somehow match BSM and Perfect Susanoo with a jutsu like that Inner Sakura summoning from the Ultimate Ninja series (it's more of a comedy based jutsu than a serious one but it's the best example that comes to mind), Sakura will remain stuck at a lower level of power. But that's not too surprising with the style of writing that Kishi uses which overemphasises the roles of the male characters.
The way i see it there are 3 choices regarding this case : 1. Shukaku 's chakra mixed with his own when he was in his mother womb. 2. Your theory and 3.Which is a combination of 1 and 2 dunno your guess is as good as mine, i hope Kishi explains this case 
I don't recall the manga or Databooks saying that Karura was ever infused with Shukaku. Gaara was first exposed to the bijuu after he was born.
I think you are exaggerating the pollen and the Hotei . Wood style does have a weakness toward fire and wind not to mention things like jinton or any kind of a explosive jutsu , while powerful yes they are not on the scale as the Shinsusenju , the only thing that can destroy that thing is either a Bijuu Dama or some kind of giant Wind or Storm jutsu like Ten pen chie.
Naruto doesn't have any counters to Mokuton though. Almost every time he went up against it, he was promptly taken out. The one time he was able to destroy a Mokuton jutsu, it left him exhausted and unable to stand on his own. Granted, it was a clone who was weak and being supplied with Kurama's chakra that handled that situation, but Naruto's limitations are very much apparent. Naruto doesn't have the expertise or stamina to handle Hashirama. With the amount of chakra that man has and the scale of his jutsu (even without Shinsusenju), he's a mutant.
