It could also be due to a prophecy. If there was a prophecy that Naruto would bring great disaster to the village in the future, his parents, who are responsible for the village's well - being, might choose to banish him. They would be in a difficult position, having to choose between their love for their son and their duty to the village. However, this is a very hard decision and would likely be full of internal conflict for them.
One possible reason could be that Naruto discovers some dark family secret that his parents want to keep hidden. For example, if there was a connection between the Uzumaki clan and some forbidden jutsu, and they fear Naruto might be exploited because of it. So they banish him to protect the clan's reputation and his own safety.
Maybe Naruto's parents believe he has some uncontrollable power within him. In the Naruto world, powerful and unpredictable abilities can be very dangerous. His parents might think that by banishing him, they can prevent him from accidentally harming the village or those around him. They may hope that in exile, he can learn to control this power on his own without endangering others.
