Famously Libertarian sci-fi author Robert A. Heinlein was always a radical. Earlier in his life he worked, and stood in elections, for the Social Credit movement. Indeed, his early, previously unpublished, novel For Us, the Living was based around a US that had adopted the SoCred doctrine.
In the novel, in the 1950s, Fiorella LaGuardia (mayor of New York when Heinlein was writing) begins a series of economic reforms, starting with a banking system based on the Social Credit theories of Socred thinker Clifford Hugh Douglas. In the novel, the U.S. Supreme Court upholds these changes. In reality, in Canada, the Supreme Court rejected them.
In For Us, the Living, later presidents complete the reforms. These reforms then give people a basic income that bridges the gap between production and consumption, which then allows the Americans of 2086 to do what they really want, free of economic fear.
