This is what I always wanted to see. Municipalities running federated servers. Solves the problem of "which server do I pick" and also gives user guarantees that are tangibly bound to real entities.

I think a whole nation is too big for one server of course. But some kind of breakdown based on reasonable subsidiarity would be great. In the US, maybe it would be counties. Sort of like phone numbers, you may choose to keep your original area code even after you move, or eventually maybe you update and move your account to the new server when you settle in.
