The right to use force to defend rights may be derived immediately and trivially from the very idea of enforceable rights. If we have any enforceable rights at all, we have the right to use force or threats of force to defend them. That is what enforceable means. If we don't have any enforceable rights, then the whole idea of justice is empty. But the right to use force to rectify rights violations and the right to use force to punish rights violators are not so easy to establish.
Justice is respect for the rights of individuals and associations .
The right of several property specifies the right to acquire, possess, use, and dispose of scarce physical resources including their own bodies. Resources may be used in any way that does not physically interfere with other persons' use and enjoyment of their resources. While most property rights are freely alienable, the right to one's person is inalienable. The right of first possession specifies that property rights to unowned resources are acquired by being the first to establish control over them and to stake their claim. A manifestation of assent is ordinarily necessary unless one party somehow has access to the other's subjective intent.
