I mean this very kindly when I say, who the hell cares about the fanfiction aspects? Most writers (some more than others), despise fan fiction as terrible disrespect of their work, so I don't think Kishimoto is sitting around worrying about those of us who write fan fiction. And frankly, if your world is turned upside down by a fictional pairing, you need psychiatric help.

The fan base matters very little here, as far as considerations for an ending go. This is how Kishi decided his manga should end, so he did.
