A libertarian revolution has two components: ideological and institutional.
Ideologically, we can promote laissez-faire capitalism and Rothbardian natural law.
Institutionally, it seems obvious that the US federal government is unreformable. It must be destroyed utterly. David Gornoski has put the matter this way:
The answer to globalism is nationalism.
The answer to nationalism is localism.
The answer to localism is your property.
I have been a “city-state libertarian” for a very long time. This is consistent with Mises’ position on secession, namely, that
the right of self-determination… is not the right of self-determination of nations, but rather the right of self-determination of the inhabitants of every territory large enough to form an independent administrative unit.
If it were in any way possible to grant this right of self-determination to every individual person, it would have to be done.
This is impracticable only because of compelling technical considerations, which make it necessary that a region be governed as a single administrative unit and that the right of self-determination be restricted to the will of the majority of the inhabitants of areas large enough to count as territorial units in the administration of the country. (Liberalism, 109-10)
A city, in my opinion, is both necessary and sufficient to provide almost all the essential government services. There is no need for any government larger than what we understand as “local.”
Within these hundreds of thousands of towns, libertarian ideology needs to be fully accepted.
A final key libertarian political institution is fully private (not merely “independent”) judiciary. It was a major error on the part of the founders of the United States to put judges on the government payroll. It has resulted in the state becoming its own judge.
Regarding the “open borders” problem, in a fully libertarian world in which massive inequalities in the standard of living between cities are not observed, there ought to be 100% open borders on the level of cities; but the borders of any smaller explicit private community or organization within a city will be managed entirely by the property owners.
