The whole "let's have lots of micro-states with easy exit" condition proposed by these advocates here sounds borderline quasi-plausible, IF somehow you could get that going to begin with (not bloody likely)... but even from a purely economic perspective, the transaction costs in choosing a new place to live and moving there are very high, so one would suspect this layout would lead to inefficient results. (and that's economic efficiency, which includes your overall well-being.) And who enforces that you get to up and leave whenever you want, anyway? The other micro-states, using WAR?
