Privatism is a generic term generally describing any belief that people have a right to the private ownership of certain things. There are many degrees of privatism, from the advocacy of limited private property over specific kinds of items ( personal property) to the advocacy of unrestricted private property over everything; such as in anarcho-capitalism. Regarding public policy, it gives primacy to the private sector as the central agent for action, necessitates the social and economic benefits for private initiatives and competition, and "legitimizes the public consequences of private action."
