Not being able to leave the country is the clincher for me. No thanks, there are too many exciting things to see and i fail to see what I could have more of now in terms of luxuries that would make me any happier.
I'm going on the assumption that such an utopian society is founded on a global position as everyone would want to live in such a benevolent and "land of milk and honey" society and in that benevolence no-one, be it individual or nation would be refused...thus you would be able to travel wherever you so wished without ever leaving the country as the country would be the world.
