So there's something I've been wondering for a while, and I just never got around to researching or asking, so, here goes.
If people can remove and seal tailed beasts without dying (the Sand and Cloud Villages did this), then why did Minato use the reaper death seal to seal the Nine-Tails into Naruto? Kushina taught him lots of sealing jutsus, right? Could he have used a different one? I mean, he was willing to sacrifice himself to be able to seal some of Kushina's chakra into Naruto so she could meet him, but I think it would've been better for Naruto to grow up with at least one parent than none but to be able to see his mom for five minutes.
Anyway, that's my question. Is there a reason for this, or is it just a plot hole?
