A voluntary society, voluntary community or voluntary city is one in which all property (including streets, parks, etc.) and all services (including courts, police, etc.) are provided through voluntary means, such as private or cooperative ownership. In a voluntary society, the notion of something being "privately" or "cooperatively" owned would be radically different from monopolistic "privatization" with state subsidies, or monopolistic control of public resources by the state, respectively. Instead, courts might be replaced with dispute resolution organizations; police with volunteer-based community defense organizations or private security agencies and crime insurers; transportation authorities with community road associations and rail counterparts; etc. These services were the subject of the book, The Voluntary City, which dealt with them chapter-by-chapter.
