I agree, however when you look at other Western countries, these kinds of laws are quite tenable, and in fact, some similarly onerous laws have been implemented or trialed in a limited capacity in places like the U.K. I merely wished to point out the value in a recognised right to free movement that so many people take for granted. I feel that in a place like the U.S. this kind of posturing would simply be a non-starter, because it's basically a totally untenable threat.
