Voluntaryism is based on the moral principle that each person owns himself, isn't a slave to anyone else for anything. That infers the moral right to self-defense and defense of others whenever that principle is violated. It also implies that each owns the fruits of his labor, and has the moral right to freely transact such fruits with others in ways that don't violate the self-ownership of others. It also implies that no one has a right to the fruits of another's labor. Personal responsibility. Live and let live.
