HOPPE: Mises thought it was necessary to have an institution that suppresses those people who cannot behave appropriately in society, people who are a danger because they steal and murder. He calls this institution government.
But he has a unique idea of how government should work. To check its power, every group and every individual, if possible, must have the right to secede from the territory of the state. He called this the right of self determination, not of nations as the League of Nations said, but of villages, districts, and groups of any size. In Liberalism and Nation, State, and Economy, he elevates secession to a central principle of classical liberalism. If it were possible to grant this right of self-determination to every individual person, he says, it would have to be done. Thus the democratic state becomes, for Mises, a voluntary organization.
