and ownership claims on land and natural resources as immoral and illegitimate, seeing the idea of perpetually binding original appropriation as advocated by some anarcho-capitalists as anathema to schools of anarchism as well as to any moral or economic philosophy that takes equal natural rights to land and the Earth's resources as a premise. Left-wing market anarchists are closer to mutualism and part of the market anarchist tradition in arguing that a true free-market or laissez-faire system would be best served under socialism rather than capitalism. Chartier has argued that anarcho-capitalists should reject capitalism and call themselves freed-market advocates, writing: [I]t makes sense for [freed-market advocates] to name what they oppose "capitalism." Doing so calls attention to the freedom movement's radical roots, emphasizes the value of understanding society as an alternative to the state, underscores the fact that proponents of freedom object to non-aggressive as well as aggressive restraints on liberty, ensures that advocates of freedom aren't confused with people who use market rhetoric to prop up an unjust status quo, and expresses solidarity between defenders of freed markets and workers — as well as ordinary people around the world who use "capitalism" as a short-hand label for the world-system that constrains their freedom and stunts their lives. Criticism of anarcho-capitalism Anarchists argue that anarcho-capitalism does not in fact get rid of the state and that it simply privatises it. According to Brian Morris, anarcho-capitalists "simply replaced the state with private security firms, and can hardly be described as anarchists as the term is normally understood". According to anarchist Peter Sabatini, anarcho-capitalism "represents a minority perspective that actually argues for the total elimination of the state", but that anarcho-capitalists' claim as anarchists is "quickly voided" because they "only wants an end to the public state" and allow "countless private states", or that it dissolves into city states as argued by Paul Birch. Another criticism is that anarcho-capitalism turns justice into a commodity as private defense and court firms would favour those who pay more for their services. Anarchists such as Albert Meltzer argue that since anarcho-capitalism promotes the idea of private armies such as private defense agencies, it actually supports a "limited State". Meltzer contends that it "is only possible to conceive of Anarchism which is free, communistic and offering no economic necessity for repression of countering it". Anarcho-capitalists believe that negative rights should be recognized as legitimate, but positive
