Free market anarchism or Anarcho
capitalism is an umbrella term for a number of ideologies which believe that there should be no government, and a free market economic system, as opposed to anarcho
socialism, anarcho
communism, and anarcho syndicalism which focus on shifting ownership of property, companies etc. to the masses. Anarcho socialist types believe "Property is theft" while anarcho capitalists believe "property is freedom". Anarcho capitalists believe that a free market is the only truly anarchist economic system. The concept was popularized by Murray Rothbard of the Austrian School of Economics.
