Libertarianism is not and does not pretend to be a complete moral, or aesthetic theory; it is only a political theory, that is, the important subset of moral theory that deals with the proper role of violence in social life… Libertarianism holds that the only proper role of violence is to defend person and property against violence, that any use of violence that goes beyond such just defense is itself aggressive, unjust, and criminal. Libertarianism, therefore, is a theory which states that everyone should be free of violent invasion, should be free to do as he sees fit except invade the person or property of another. What a person does with his or her life is vital and important, but is simply irrelevant to libertarianism.
