The Naruto series as a whole is mainly based on Naruto's life in the Leaf village. Locking clans to villages would be unwise because, by default, Leaf has more detailed-out clans and also, it will restrict diversity. Making a clan like Uchiha available after 3 months is also not a good idea. They already have this "exclusive" appeal and to solve that you want them to be even more exclusive? That's just going to backfire so miserably. The idea of players creating their own clans doesn't really appease me either. It's just off-tangent. The concept of Naruto being ninjas from different clans and villages fighting each other. If one could just go ahead and create their own clan, what would be the purpose? The concept partially borders on the stereotype that once you are born into a family, you gain certain advantages and disadvantages. Things are expected of you. If you could just up and go do your own thing, it would deafeat the purpose. I honestly want to know the plan for Clans in the game so if anyone has a topic he/she could link me to, I would be very grateful.
