Maybe it's due to a misrepresentation of Naruto's character. In the official Naruto series, he is a hero who is deeply connected to Konoha. If the fanfiction shows him in a negative light without proper justification, like suddenly turning against Konoha for no good reason, it could be banned. Also, if the fanfiction involves some sort of political incorrectness within the context of the Naruto universe, such as discriminatory ideas towards certain clans in Konoha, that would be a reason for a ban.
On one hand, it may split the fan community. Some fans might support the ban, believing that it's important to uphold the positive image of Naruto and Konoha. Others might be against it, thinking that fanfiction should be a place for unrestricted creativity. This can lead to debates and discussions within the community. Also, it might inspire some fans to create their own fanfictions that explore the 'naruto banned from konoha' concept in a more acceptable way, which could bring new ideas and interpretations to the community.
Maybe he feels betrayed. In the original story, Naruto has faced a lot of discrimination in Konoha when he was young. So in the fanfiction, it could be that some similar or new issues make him decide to hide.
One reason could be that he feels misunderstood by the villagers. Despite all he has done for Konoha, some still hold grudges or are afraid of his power. Another might be that he wants to explore the world on his own terms, away from the responsibilities and restrictions of Konoha. Maybe he also feels a sense of loneliness there, as he has lost many important people and the village constantly reminds him of those losses.
One reason could be that it's overused. If there were too many fanfictions focusing on Naruto and ramen, the community might want to encourage different storylines.
It could be that Konoha wants Naruto to use his influence to bring peace among different clans. Naruto is well - liked and respected, and his words might carry a lot of weight.
In this fanfiction, it could be that the Sith from Star Wars somehow make an alliance with the dark forces in Naruto's world. Konoha then has to rely on both their ninja skills and some newfound Star Wars - like technology or magic that has also been brought into their world. For example, lightsabers could be modified to be used by ninja, and the Force could be a new power source that some characters start to explore.
It could mean that in the world of fanfiction related to Naruto, there are certain restrictions or bans on stories involving Naruto and ramen. Maybe the creators of the fanfiction community have some rules against this particular combination for various reasons, like they want to focus on other aspects of Naruto's character or storylines.
Well, in some fanfictions, Naruto might outsmart Konoha by using his unique knowledge of the village's secrets that others don't know. For example, he could use his understanding of the old tunnels under Konoha to his advantage in a situation where he needs to escape or gain an upper hand in a conflict.
From a security perspective, Konoha would be weaker. Naruto is a very powerful ninja, and Hinata is no slouch either. Their skills and abilities would be missed. Enemies might see this as an opportunity to attack Konoha. Also, Naruto has been a symbol of hope for the village. His departure could lead to a decrease in morale among the villagers. They might start to feel less secure and more pessimistic about the future.
