Because I never said they were exactly the same. The scenario was to give perspective, Gohan didn't train and thus got weaker.
The Gohan argument made no sense because as I already said, it's the equivalent of Naruto's chakra potency growing from one second to the next. It doesn't give perspective because it's not comparable at all. Naruto doesn't grow stronger at all, he simply is more determined to win. That does not, in any way, mean he becomes stronger.
Yes, but it's much more trivial when we're talking about people with Rikudo chakra. In terms of potency, there's people much weaker than Naruto ahead of half Kurama in potency.
Not really. Juubi is made of the 9 tailed beasts and Hagromo's chakra is basically like the Juubi's chakra. Half of the Kyuubi was a huge boost in power given how much stronger Madara was then Obito. Half of the Kyuubi is half of the Kyuubi, regardless of how you look at it there's a substantial boost in both chakra quantity and potency since Kurama's chakra also acts as a multiplier. SM boosts anybody because it's a multiplier, Yin-Yang cloak>Yang cloak, etc..
But it would have deteriorated from not training. Simply growing older wouldn't make up the diffrence. A 30 year old thay does nothing all day is going to be in worse shape than his 16 year old self that had football practice everyday. I doubt the Boruto movie was his prime, his Last self would be under non-nerfed circumstances if anything.
True, but that's only Gaiden. However Naruto did it, he was obviously extremely adept at fighting in the Boruto Movie. There's even a scene of his insane level of Kenjutsu skills so saying he was rusty despite the skills displayed is rather against what was being portrayed. If anything, the Boruto Movie Naruto is a lot stronger based on his base chakra boosting Boruto's rasengan an INSANE amount and him having the 100% Kyuubi with him. Also, he displayed feats of BM manipulations that he had never shown before, clearly he had learned some things whilst he wasn't Hokage for 2 years. Boruto Movie shows Naruto in his prime, based on feats. No way anybody can deny this, and I haven't even seen all his feats.
Again I wouldn't know, he had enough time for Boruto to graduate from the academy for sure though. That's if he did.
Alright, I feel like you shouldn't be arguing Boruto Naruto
not being in his prime if you haven't even seen the movie. Sasuke just improved an immense amount and closed the gap with Naruto. He has a gigaton base Chidori from the Last and as speed on par with Naruto's, both of which are absolutely insane. Also, that means his PS Chidori would be dramatically more powerful then Indra's Arrow.
