geographical regions should have the right to independence
Geographical regions, and perhaps other forms of social groups, should have the right to independence. Texas should be allowed to secede from the US, Catalonia should be allowed to secede from Spain, etc. Secession mechanisms should probably be somewhat arduous and they should take time, but they should exist. Otherwise, populations are forced into a government; we are no longer servants, but we are forced citizens.
Pre-arranged exit plans also give a chance to peaceful resolutions of independence claims. It's the only way we can stand against violent approaches, by providing an alternative.
