One reason could be that Naruto has his own independent goals. He's always been determined to become Hokage. Maybe the team's goals don't align with his. For example, if the team is more focused on short - term missions for money rather than long - term village development like Naruto wants.
The plot could take a darker turn. Without Naruto in the team, the team might struggle to complete important missions. This could lead to negative consequences for the village, like losing territory or influence. For instance, if the team was supposed to protect a key trade route and fails without Naruto.
Well, Naruto has his own journey and story arc in the original Naruto series. The 'cra fanfiction' might deviate too much from what he has experienced and learned. He has grown up with certain beliefs and goals, and if the fanfiction doesn't respect those, he'll refuse it. Additionally, he might be concerned about how such a fanfiction could influence the perception of his friends and the village he loves. If it portrays them in a negative or inaccurate light, he would surely stay away from it.
The fanfiction could be presenting a version of Naruto that doesn't align with the canon. In the official Naruto story, he has a specific growth arc and personality traits. If the 'cra fanfiction' changes these too much, it's like creating a different character altogether. Naruto, as we know him from the original, would not be part of such a misrepresentation.
Perhaps the fanfiction doesn't respect the world - building of the Naruto universe. Naruto has a deep connection to his world, from the hidden villages to the different jutsu. If the fanfiction messes with these fundamental aspects, for example, by creating new and illogical rules for chakra or changing the relationships between the villages in a wrong way, Naruto would not accept it as it goes against what he knows and loves about his world.
One possible reason could be that Naruto wants to develop his own unique ninja way without relying on the traditional toad contract. He might feel that it would limit his growth in a sense.
The scenario where Team 8 saves Team 7 instead would be quite interesting. It could introduce new conflicts and resolutions, and potentially reveal hidden strengths of Team 8 that weren't previously showcased.
One way could be simply stating that you don't like the character of Jafar enough to engage in fanfiction about him. For example, 'I'm not a fan of Jafar, so I won't be part of any Jafar fanfiction.'
Kurenai might be a good sensei for Naruto's different team. Her expertise in genjutsu would be valuable. She could help the team develop their skills in this area, especially if the new team members have some potential in genjutsu. Kurenai is also very perceptive, which would be great for guiding Naruto and his new teammates through difficult situations.
