Because of the inherently good nature of humanity, the basis of Libertarian assumptions. P.S. Do note that the platform of the Libertarian Party of Colorado explicitly denies that the government has a monopoly on violent force, does not allow the government to initiate violence, and in fact, doesn't describe any way of paying for what force the government may legitimately apply. Enforcing any of your rights requires you to be a part of a more powerful gang than theirs.
