Naruto could try to change Konoha from the outside. He might form an alliance with other villages or groups who share his views on how a village should be run, and then use their combined influence to force Konoha to make changes.
His relationship with his friends and former comrades could become strained. Some might understand his reasons for being tired of Konoha, while others might see it as a betrayal, which could lead to conflicts among them.
