Another reason could be related to a prophecy or a misunderstanding of one. If there is a prophecy that Naruto will bring great change, but some misinterpret it as a negative change. They might fear his power and potential influence, and thus force him to leave Konoha.
One possible reason could be false accusations against him. Maybe he's wrongly blamed for a crime he didn't commit, like being framed for a major attack in the village. This would lead the village leaders to force him out to maintain 'peace' and security.
It might be due to political reasons within Konoha. There could be a power struggle among the different clans or factions. Naruto, being a powerful and somewhat unpredictable force, could be seen as a threat to those in power who want to keep things as they are. So they force him to leave to solidify their own positions.
