The same opportunities exist for libertarians. If they object to this market of contracts for any reason, then they must explain why recreating the same system on a smaller scale would prove any better. Put another way, the objection to moving is inconsistent with the libertarian goal of awarding individuals sovereign rights to their property, since that would essentially recreate the market of nations on a smaller scale in our society. That is, landlords and business owners would become the rulers of their own pocket principalities, and renters and workers who disliked their conditions would simply be advised to look elsewhere on the market for jobs and apartments. Libertarians balk at the same principle on a larger scale, but they can't support a market of sovereign property owners only in those cases where it suits them.
Libertarians also object that there is no libertarian country to emigrate to.
And although libertarians may not find their desired nation, they would in fact find many nations with greater libertarian features than the U.S. Many Third World countries, for example, have far smaller tax rates and public sectors than ours. Most are less burdened with business regulations. Chile, for example, underwent 17 years of radical free-market reform under the guidance of the University of Chicago, and reduced its government as much as was humanly possible. Some, like Somalia, even practice pure anarchy and Social Darwinism. Of course, few people would want to live in these places.
