Just to clarify I was refering to government monopolies, sorry if I wasn’t clear. Mises is not perfect Autolykos, so if that isn’t the definition of Socialism then it should be.
Various “Libertarians” (George Mason Austrians for example) are just socialists in the long-run. Also the government is too incompetent from keeping most rich people from moving. And also other governments will use other currencies eventually.
