The consequences could be far - reaching. Naruto's actions might cause a rift between different factions in Konoha. Some might understand his reasons for protecting Hinata and leaving, while others would see it as a blatant act of disobedience. He would have to start from scratch in building a new life outside Konoha, all while being hunted or at least being watched closely by Konoha's forces. His reputation would be severely damaged, and he'd have to prove himself all over again in the eyes of the ninja world.
Well, one possibility is that Naruto has some secret mission or personal reason for leaving Konoha that he can't share. He takes Hinata with him because he has deep feelings for her and wants to protect her. Maybe he believes that Konoha is in some kind of danger that he can't prevent while staying there, so he decides to take Hinata and start a new life away from the village.
One possible reason could be for his safety. Konoha is a well - protected village with many skilled ninja. She might believe that leaving him there would ensure he has the best chance at survival and growth as a ninja. Also, she may have some mission or obligation that forces her to leave him behind, perhaps something related to the greater good of the village or the ninja world in general.
One reason could be to find a more peaceful place. Maybe after all the chaos in Konoha, they just want a quiet life away from it all. They might also leave to explore the world and discover new things together, like new jutsus or different cultures.
Economically, there could be some impact as well. Naruto and Hinata are popular figures, and their presence in Konoha likely contributed to the local economy in some ways, such as through tourism (people coming to see the famous Naruto). Their departure might cause a dip in certain sectors that relied on their popularity, but it could also open up opportunities for new shinobi to rise and bring in new sources of income for the village.
Perhaps Hinata leaves Konoha pregnant because she feels she doesn't fit in anymore. She may have faced discrimination or coldness from some of the villagers. So, she decides to leave and find a place where she and her baby can be accepted for who they are. She could end up in a community of outcasts where she finally finds true friendship and support.
In some fanfics, Naruto might leave Konoha as a child because he feels ostracized. Since he's the jinchuriki of the Nine - Tails, many villagers fear and shun him. He could get tired of the constant cold shoulders and decide to leave in search of a place where he'll be accepted.
One possible reason could be for Naruto's safety. Maybe she has to go on a dangerous mission and believes Konoha is the safest place for him. Another reason might be that she is forced by some powerful enemies who threaten Naruto's life if she doesn't leave him in Konoha.
One potential consequence could be widespread destruction. The Kyuubi is an extremely powerful force. Buildings would likely be demolished, and many shinobi might be injured or killed trying to combat it. Another consequence could be a shift in the power dynamics within Konoha. Some might see Naruto as a threat, while others might try to use this situation to gain power themselves.
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.
One possible plot could be that Naruto and Samui are on a mission outside Konoha when they receive some crucial information that puts Konoha in danger. However, they realize that there are traitors within the village who would stop them from using this information to save it. So, they decide to leave Konoha temporarily to gather more evidence and allies. Along their journey, they face various challenges and also start to understand each other better, with Naruto's determination rubbing off on Samui and Samui's calm and strategic thinking helping Naruto in different situations.
