They sound like the Mutualists, of whom I know one (he's in the same political party as me, hilariously.)

As far as I can tell, Mutualists = Market anarchists who believe local judges (who aren't officially given any power) and embarrassment will keep everyone behaving ethically - no need for formal laws or governments. It seems a very very deep misunderstanding of the role of weak-tie trust in economics to me.
