I've chosen "GTFO" long time ago (and I wish i did it even earlier, and will kick my own children out ASAP), and I wish I could do the same with government. But unlike parents, the government(s) wouldn't simply let me out. The best thing I could do is emigrate, but outside of my government there are only another governments, most of them are even worse one way or another (especially those which would let me in easily). That's why the right to secede is probably the most important of my goals as a political activist.
You already won three internets for staying consistent. But a problem with your last sentence. Don't tune out -- this is shorter than it looks
When you decided to GTFO of your parent's, you didn't get to take your room with you -- it was an integral part of your parents' house.
Your new place [apartment, friend's house] had rules too.
Just like GTFO of your country will land you in *another* country with lawns to cut. The analogy holds.
It's hard to tell just what you mean when you say "[your] right to secede," then.
You admit that your government will allow you to emigrate, what more do you want? You can't fault it for the world outside of its borders. No more than your parents are at fault for the world outside their house sucking & the rent being expensive. Agreed?
Just how exactly do you wish to "secede"? Keep in mind some very basic concerns:
When you "own" an apartment, you can't "opt out" of maintenance costs for the building (think tax), nor can you take your walls and ceilings with you if you leave -- those walls are *also other people's walls,* a structural part without which the whole building will fall apart.
Is something like this your idea of "seceding" ? You want more stuff to take with you? Otherwise, the world is your oyster! Earth's taken, not sure about the moon, but the rest of the universe is yours for the taking! Go forth and live free amongst the starz!
