“That initial premise is that each of us owns himself. Stated another way: I am my private property and you are yours. The institution of private property is the right held by the owner of property to keep, acquire, dispose, and exclude from use. The premise of self-ownership determines which human acts are moral or immoral and consistent with that premise. For example, rape, murder, slavery, fraud, and theft are immoral because they violate private property.”
