In light of the above, and to respect the rules in place, I will actually take some time to directly discuss the subject at hand then, elaborating on my original post, while also blowing out some smokescreens and speaking on the truth of things.
NS did not "die", because in a romantic sense, the fandom still exists, this forum still exists, fan-fiction still exists, etc. The idea of a world with these two people getting together for fans did not die. The shipping of NS won't go away. That was born on chapter 3, and will always have a following.
In regards to the manga, NS did not die, because in a narrative sense, it was never born. It was at most a consideration, by Kishimoto's own words. He made plans, but allowed for organic growth of the characters to change things, and as time went on, the idea of NS did not work for him, and so he did not give it life, and canonically, Naruto's crush faded. Nothing was stolen from us, we were never entitled NS. Swapping 700 with NS at the end wouldn't make the ending make more sense, but the inverse. It's not that it wasn't resolved, it very much was. Kishimoto added a specific scene in the Last to explain this further, but you don't need it, and it was there for those who didn't quite understand, to offer a more full sense of closure. In a sense, if we are talking about the possiblity of NS, then it died narratively in 469.
But for readers, this obviously varies between who you ask. For some it is 469, for others, 693, for yet others, 699, 700, 615, part one, some as what the Last was about came to be revealed, or so many other points. I think for those in echo chambers, it followed the general consensus. For many that would be at 700, or the revelation of the leaked pictures, to be more specific. i myself, was not absolutely sure, until the end, doubt only empowering faith.
Despite the lack of NS, The end resolved the major points, tied the major points together, and was good closure. There might have been no NS, but I'm happy with what was delivered.
