I don't think that makes much sense. Imagine people coming to your house and declaring you, they are not bound by your home rules, but rather their own rules - so they start a trash party now.

In other words, I think it very much makes sense to bound land and rules. Exception might be nomadic people, like beduins travelling through the desert: when you come to their tents, you are bound by their rules, even though the tents change place.

And dispossessed peoples like the Rohingya in Myanmar, or the Kurds who live in 3 different countries and are not particularly well liked by any of their 'hosts'; the Uyghurs in China.

But people have to live somewhere, and places have governments, and governments may not like some people.

Which is a reason I like the idea of federalism with much more power on the base. Basically, small, but connected states, so chances are higher, the local government represents the local people.
