anarchism, which is the ultimate form of self-determination. Essentially, its shrink the size of a nation down until every individual is a nation.
No government, except by free association. This basically means that you are free to do whatever you want so long as you don't infringe upon someone else's freedom, and when stuff needs to get done in an organized fashion (that is, in groups) the "government" rules only with people's direct permission, and anyone who does not agree is free to leave the group, and thereby the jurisdiction of the "government" and go do their own thing.
The problem with this is, taken literally, any unwanted influence by another person could be seen as an infringement of your rights, which in theory means we'de all have to live on seperate planets. However, thats where the free association bit comes in, since people would be free to accept that living together is an integral part of being human, and thus would accept the small but inevitable bits of influence that come with living together.
For you righties: go far enough to the right, shrink the government's role down enough, and you get anarchism.
