Well as an anarchist social analysis is rights are a construct and likely not the same in any two nations, and liable to change with social attitudes. Some may view or expand rights to things such as healthcare, job guarantee, free access to natural resources etc…. This is why I’m a Georgist, Physiocracy has always been the radical wing of liberalism. American fathers like Paine, Jefferson, Franklin were physiocrats who argued for the commons of natural resources and public compensation for land rights in a ground tax. Georgists called it the Single Tax, while enterprise goes on unencumbered by taxation. Also yes freedom of movement is a core principle of economic liberalism.
