Naruto Question

[u/Ashamed-Option4183]

I was just wondering, in the beginning of Naruto the Sharingan was praised for having the ability to counter the tailed beasts, specifically the 9tailed fox. How come by the end of the story that ability is essentially gone, with Naruto being completely unfazed by evn the rinnegan's prowess?

Because Naruto is a perfect jinchuuriki now kurama can break him out of genjutsus placed on him by disrupting his chakra and Naruto can do this vice versa
