What is the point of wanting to improve a community but not associating yourself with it? That is hella backwards to me.

But again, if you create an island, people will try to come to it. And when you have to draw lines there, you fuck people all over again,.

The government you pay taxes to and the laws that the police enforces

You don't have to fuck over another one. Historically that is what happens, and it cannot be discussed away that most of Europe's wealth is built on exploitation.

But, for example, why should Sweden be a better place to live than the rest of the EU, or the world? It doesn't even make sense to me to draw these arbitrary lines. What changes when you cross the border to Finland for example?

I do not believe that the only way to improve a country is to fuck over another one. That is the easy route most people take though. But not the only one.

You can critique and improve the country and community around you to improve it without associating with it.
