"Most such intervention is tacitly assumed by mainstream right-libertarians as part of a 'market' system. Although a few intellectually honest ones like Rothbard and Hess were willing to look into the role of coercion in creating capitalism, the Chicago school and Randroids take existing property relations and class power as a given. Their ideal 'free market' is merely the current system minus the progressive regulatory and welfare state - i.e., nineteenth century robber baron capitalism."
Discussion
"But genuine markets have a value for the libertarian left, and we shouldn't concede the term to our enemies. In fact, capitalism - a system of power in which ownership and control are divorced from labor - could not survive in a free market. As a mutualist anarchist, I believe that expropriation of surplus value - i.e., capitalism - cannot occur without state coercion to maintain the privilege of usurer, landlord, and capitalist. It was for this reason that the free market anarchist Benjamin Tucker - from whom right-libertarians selectively borrow - regarded himself as a libertarian socialist."
