No, what would happen if everyone did that is that a lot of people will say "oh, <insert country here> is doing a really good job at maintaining freedom", and so a bunch of freedom nuts move there and (we're assuming everyone does it, remember) that'll be a large- and passionate-enough niche (they're passionate enough to move for better freedom, remember) that they'll have influence over the government and be able to keep it from happening. Also, as much as we hate to admit it because it makes us feel insignificant, "if everyone does it" is not a very good way to make decisions. Unless you have a lot of influence over many, many other people, nobody else is going to do it just because you did it.
