its income entirely from coercion, in the form of taxation, which Rothbard describes as "compulsory seizure of the property of the State's inhabitants, or subjects." Some anarcho-capitalists such as Rothbard accept the non-aggression axiom on an intrinsic moral or natural law basis. It is in terms of the non-aggression principle that Rothbard defined his interpretation of anarchism, "a system which provides no legal sanction for such aggression ['against person and property']"; and wrote that "what anarchism proposes to do, then, is to abolish the State, i.e. to abolish the regularized institution of aggressive coercion". In an interview published in the American libertarian journal The New Banner, Rothbard stated that "capitalism is the fullest expression of anarchism, and anarchism is the fullest expression of capitalism". Property Private property Anarcho-capitalists postulate the privatization of everything, including cities with all their infrastructures, public spaces, streets and urban management systems. Central to Rothbardian anarcho-capitalism are the concepts of self-ownership and original appropriation that combines personal and private property. Hans-Hermann Hoppe wrote: Rothbard however rejected the Lockean proviso, and followed the rule of "first come, first served", without any consideration of how much resources are left for other individuals, which opposed John Locke's beliefs. Anarcho-capitalists advocate private ownership of the means of production and the allocation of the product of labor created by workers within the context of wage labour and the free market – that is through decisions made by property and capital owners, regardless of what an individual needs or does not need. Original appropriation allows an individual to claim any never-before-used resources, including land and by improving or otherwise using it, own it with the same "absolute right" as their own body, and retaining those rights forever, regardless of whether the resource is still being used by them. According to Rothbard, property can only come about through labor, therefore original appropriation of land is not legitimate by merely claiming it or building a fence around it—it is only by using land and by mixing one's labor with it that original appropriation is legitimized: "Any attempt to claim a new resource that someone does not use would have to be considered invasive of the property right of whoever the first user will turn out to be". Rothbard argued that the resource need not continue to be used in order for it to be the person's property as "for once his labor is mixed
