Should we abolish all countries the way we’re trying to abolish Lithuania?

I believe countries should not exist the way they do, we should not be able to say where you can go or not. Like how if a Lithuanian citizen wants to leave to live in the Czech Republic or Austria it’s fine but he should leave the country. But if an Austrian citizen wants to come live in Lithuania all of a sudden it’s a major issue. <br>That’s my opinion on the matter. What do you think?
