There is proof:
First Oro's curse mark was said to be just a way for "the cursed" to collect Natural Energy.
And very few people are compatible with the curse mark as very few are compatible with Sage mode.
So the curse mark was simply a way to gather Natural Energy like the oil was in the beginning for Naruto.
And Sasuke is compatible with using Natural Energy - he's been using it for 3 years while Naruto has for only a month.
On the other side Naruto is compatible with the Sharingan and the Rinnegan:
- Kakashi is compatible with the Sharingan and he's 100000 times below Naruto.
- Naruto has Uzumaki/Sendju DNA
- Naruto has the body strenght and huge chakra reserves
- Nagato was an Uzumaki and used the Rinnegan pretty well
You ask why does that matter???
Well there is a lot of talk of the Sage of six Paths.
And there is a lot of talk of there being a next Sage of six Paths.
And the only way to there be a next SosP is for someone to have Senju DNA and Sharingan+Rinnegan.
Soooo... you figure it out
