anarchism in the field of politics, polyculturalism in the field of culture and feminism in the field of family and gender relations as being possible foundations for future alternative visions in these other spheres of society. Stephen R. Shalom has begun work on a participatory political vision he calls "parpolity". Free-market anarchism Free-market anarchism, based on the economic theories of mutualism and individualist anarchism, is a revival of such free-market anarchist theories. It encompasses diverse economic theories like those proposed by individualist anarchists and libertarian socialists such as the Europeans Émile Armand, Thomas Hodgskin, Miguel Giménez Igualada and Pierre-Joseph Proudhon, or the Americans Stephen Pearl Andrews, William Batchelder Greene, Lysander Spooner, Benjamin Tucker and Josiah Warren, among others; and various anti-capitalists, left-libertarians and left-wing market anarchists such as Kevin Carson, Gary Chartier, Samuel Edward Konkin III, and Chris Matthew Sciabarra. Anarcho-capitalism advocates the elimination of the public sector in favor of a laissez-faire economic system and is associated with individuals such as David D. Friedman and Murray Rothbard. In an anarcho-capitalist society, law enforcement, courts and all other security services would be funded through the marketplace rather than through confiscatory taxation and money would be privately and competitively provided in an open market. Anarcho-capitalism developed from Austrian School economics, study of law and economics and public choice theory. Since employers are generally categorised as rulers in political sociology and always in anarchist theory, anarchists do not associate anarcho-capitalism with anarchist thought. The belief in the need of a police force, a kind of centralised law enforcement, to prevent crime, whether privatised or not, has been criticised by anarchists as constituting a state since police are a group with a monopoly on force. The majority of anarchist theorists do not consider anarcho-capitalism as a part of the anarchist movement due to the fact that anarchism has historically been an anti-capitalist movement and see it incompatible with capitalism. While inspired by individualist anarchists such as Lysander Spooner and Benjamin Tucker, both espoused mutualism and criticised wage labour. Rothbard argued that individualist anarchism is different from anarcho-capitalism and capitalism because the individualist anarchists retained the labor theory of value and socialist doctrines. The Really Really Free Market movement is a horizontally organized collective of individuals who form a temporary market based on an alternative gift economy. The movement aims to counteract capitalism in a proactive way by creating a positive example to challenge
