Where is it stated that nature energy corresponds to how much chakra you have? The reason why I said they aren't equal is because that's where your argument stems from. But just by looking at feats Adult Naruto is wayyyyyyy ahead of Sasuke. Sasuke lost the only powers that made him fight equally (barely) against Naruto in VOTE2 + Naruto gained power in that fight how can you seriously think they're equal? You realize Naruto's chakra cloak was pierced by Sasuke's regular sword as an adult, right?

The literal reason why only Shinobi with large amounts of chakra can even try Sage Mode is because Nature Energy will overcome anyone without enough chakra. And Fukusaka explained that Yyou balance Nature Energy with your Spiritual and Physical Energy (chakra) to make Sage chakra.

Because the author and all characters say so. The manga has been inconsistent on both sides of the argument in terms of feats and abilities so I go by what the characters and author say.
