One big challenge would be getting recognition from other villages. They might see his new village as a threat or not take it seriously at first. Naruto would have to prove that his village is a legitimate and peaceful addition to the ninja world.
Internal disputes could also be an issue. Since the new village would be made up of people from different backgrounds, there could be conflicts in ideas and values. Naruto would have to be a strong leader and mediator to keep everyone united and working towards the same goal. He would need to create a set of laws and regulations that are fair and acceptable to all the villagers, which is not an easy task considering the diverse group of people he would be leading.
Resources would be a problem too. He needs to find ways to get enough food, water, and building materials. And he has to make sure that the villagers can support themselves in the long run. Maybe he could start some trade relations with other villages early on, but that also comes with risks as they could try to take advantage of the new village's inexperience.
One challenge could be getting the other ninja clans to accept his new clan. The existing clans have their own traditions and power structures, and they might see Naruto's new clan as a threat.
One major challenge would be getting enough resources. Building a village from scratch requires a lot of materials like wood, stone, and metal. Naruto would have to either find a way to obtain these locally or trade for them, which can be difficult. Another challenge is security. A new village would be vulnerable to attacks from other villages or rogue ninjas. Naruto would need to quickly assemble a strong defense force.
One challenge would be getting other shinobi to join. Some might be loyal to their existing clans. Also, there could be political opposition in Konoha. The elders might not be too keen on a new clan being formed.
One challenge could be dealing with jealousy from other villages. His godlike powers might make other villages feel threatened. Another issue could be managing the different personalities and abilities of the people who come to live in the new village. He has to make sure everyone gets along.
One major challenge would be survival. Outside the village, he no longer has the support system of the Hidden Leaf. He'd have to find food, shelter, and deal with potential attacks from other shinobi or bandits. For example, in the wild, he might struggle to find clean water and safe places to sleep.
Naruto could struggle with the technical skills needed for forging. Even with his determination, learning the precise techniques to shape and temper the weapons to his liking could be difficult. He might need to find an expert to teach him or learn from ancient scrolls.
One challenge would be dealing with students who don't respect his authority. Naruto was always a bit of a rebel himself, so he might find it hard to enforce strict rules. Another challenge could be teaching complex ninja techniques to students with different levels of ability.
He could start by gathering like - minded ninjas. Those who share his vision of a new kind of ninja village. He might look for people who are tired of the old ways of the existing villages, like those who are frustrated with the strict hierarchies or the constant feuding between villages.
In a fanfiction where Naruto is banished and starts a village, there would be many challenges. He would have to deal with the fact that other villages might see him as a threat. To counter this, he would need to build strong defenses. He could use his knowledge of Konoha's defenses and improve on them. In terms of the village's internal structure, he would create a council of elders, but unlike in Konoha, this council would be made up of people from all walks of life. They would make decisions together, and Naruto would be more of a guiding figure. His village would also be a place where people can come to learn about different types of ninjutsu, as Naruto would encourage the sharing of knowledge.
In this fanfiction, Naruto might gather those who also feel ostracized. He could build a village based on acceptance and equality. His new village might have unique ninja training methods that focus on individual strengths rather than just traditional clan techniques.
