Libertarianism is yet another in a long, long history of utopian philosophies; none of which has ever worked, and none ever will. And when implemented on large scale, they always end in chaos and often total hell.
Nonsense - libertarianism says no more than that the only proper function of government is to defend individual rights ... nothing utopian there. Utopianism seems to better describe the war on the as-old-as-mankind urge to chemically (e.g., alcohol) alter one's mental state.
