"If a man has the right to self-ownership, to the control of his life, then in the real world he must also have the right to sustain his life by grappling with and transforming resources; he must be able to own the ground and the resources on which he stands and which he must use. In short, to sustain his "human right"—or his property rights in his own person—he must also have the property right in the material world, in the objects which he produces." Murray N. Rothbard
