There was never any "power creep".

If Naruto & Sasuke didn't meet Hagoromo, then their power wouldn't be much different compared to their current counterparts.

BSM Naruto from The Last(which isn't much different from the current Six Paths Sage mode Naruto featwise) would be Naruto's pinnacle and Sasuke's pinnacle would be his Perfect Susano'o, just like it is now.

Their battle with Momoshiki would literally play out identically.
