It could also be that Naruto discovers some dark secrets about the origin of the ninja world that shatter his beliefs. For example, he finds out that the wars and conflicts were deliberately created by a powerful hidden group. This knowledge makes him so disillusioned that he stops caring about the things he used to hold dear, such as protecting the village and upholding the ninja way.
One possible storyline could be that Naruto has faced so many disappointments that he decides to isolate himself from the Hidden Leaf Village. Maybe he feels betrayed by the people he once trusted, like some of the village elders. He might then embark on a journey alone, exploring new lands and meeting different shinobi cultures.
Perhaps in this fanfiction, Naruto has lost someone very dear to him, like Sasuke in a more permanent way. This makes him lose all his motivation and care for the village. He could start acting recklessly, not following the rules of the ninja world anymore, and becoming a sort of anti - hero figure who challenges the established order.
