Ok, I didn't know that. - Anyway, it doesn't weaken my main argument that normally you are free to leave a nation but wouldn't have a place to go after that. - It's like terminating your rental contract. You can always do that, but as long as you don't have a new one (or at least a plan what to do after) you should probably just keep paying your landlord. :)
