relying too much on the market. Friedman responded to this criticism by arguing that it assumes the state is controlled by a majority group that has similar legal ideals. If the populace is diverse, different legal standards would therefore be appropriate. Rights and freedom Negative and positive rights are rights that oblige either action (positive rights) or inaction (negative rights). Anarcho-capitalists believe that negative rights should be recognized as legitimate, but positive rights should be rejected as an intrusion. Some critics reject the distinction between positive and negative rights. Peter Marshall also states that the anarcho-capitalist definition of freedom is entirely negative and that it cannot guarantee the positive freedom of individual autonomy and independence. About anarcho-capitalism, anarcho-syndicalist and anti-capitalist intellectual Noam Chomsky says: Economics and property Social anarchists argue that anarcho-capitalism allows individuals to accumulate significant power through free markets and private property. Friedman responded by arguing that the Icelandic Commonwealth was able to prevent the wealthy from abusing the poor by requiring individuals who engaged in acts of violence to compensate their victims financially. Anarchists argue that certain capitalist transactions are not voluntary and that maintaining the class structure of a capitalist society requires coercion which violates anarchist principles. Anthropologist David Graeber noted his skepticism about anarcho-capitalism along the same lines, arguing: Some critics argue that the anarcho-capitalist concept of voluntary choice ignores constraints due to both human and non-human factors such as the need for food and shelter as well as active restriction of both used and unused resources by those enforcing property claims. If a person requires employment in order to feed and house himself, the employer-employee relationship could be considered involuntary. Another criticism is that employment is involuntary because the economic system that makes it necessary for some individuals to serve others is supported by the enforcement of coercive private property relations. Some philosophies view any ownership claims on land and natural resources as immoral and illegitimate. Objectivist philosopher Harry Binswanger criticizes anarcho-capitalism by arguing that "capitalism requires government", questioning who or what would enforce treaties and contracts. Some right-libertarian critics of anarcho-capitalism who support the full privatization of capital such as geolibertarians argue that land and the raw materials of nature remain a distinct factor of production and cannot be justly converted to private property because they are not products of human labor. Some socialists, including market anarchists and mutualists, adamantly oppose absentee ownership.
