On the temporary nature of structures

I've frequently argued with many people about things which ultimately end up in a discussion about nationalism. One aspect is legislation: if I'm a member of a group of people occupying a piece of land and wish to remain a member of the group, I will naturally have to adhere to some types of rules. If I don't adhere to them, there are typically some types of consequences. In nature this consequence is often expulsion from the community. And in our world can typically range from reprimands and fines to imprisonment or even death (which I don't necessarily agree with).

So what can one do if one doesn't agree with the rules? The most obvious choice is always to accept that it's a trade-off situation: I will have to accept them to get the other benefits of staying with the group. So in short: do nothing. The second choice is to do something about it, i.e. attempt to reform legislation, change taxation, or do something else. So essentially bitch and moan and propose alternative solutions and apply all the rhetorical tools that you have available to you. Or thirdly you can agree that you have differing views with the rest of the group and accept that you do not wish to be a part of the group any longer and find a new group to join. There may be other options as well, but these are the blindingly obvious ones.

It is the third option which typically tends to cause the most friction with the people who I've discussed. I think the issue is that very many people can or do not want to question the concept of a nation. The problem arises when someone suggests that maybe the concept of a sovereign nation is something that should be challenged: the world should be a lot more fluid and enable us to disband with the concept altogether. Maybe that is a bit radical, but on a more tangible level I think that I personally should be able to change my citizenship if I do not agree with what the rest of the group that forms a nation is doing. Ultimately, however, I think that a nation is merely a temporary structure that is useful as long as it serves a purpose. It is a mean to an end, but not a purpose in itself. Similar to any sort of alliance between entities, but still ultimately temporary in nature, even though nations are a lot more long in duration than other structures.
