By being both anti-authoritarian and anti-corporate monopoly, Left Libertarians present a clean break from right-wing coalition of neo-cons, the Religious Right, and Big Business. In opposing the war, in promoting local control (which many Greens do), in fighting state-sanctioned corporate privilege, and in fighting to protect our civil liberties, the Libertarian Left has far more in common with the Left than with the Right as it is presently identified.
What this does not mean is that I prefer Hillary to Congressman Ron Paul. It does not mean outright partisanship in which liberals are my friends and conservatives my enemies. I still feel a sense of common cause with many on the Right, especially strict Constitutionalists. But historically the Right has been the party of the Establishment, of landed privilege. The Left has been opposed. Libertarianism ultimately belongs on the Left.
Among his list of issues distinguishing left-libertarians from the mainstream libertarian right, this is my favorite:
3. a)A utilitarian capitalist ethic which "encourages" arts and inventions through federally-protected patents and copywrights and the government protection of "limited liabiity" in which stockholders are not personally responsible, and therefore indifferent, to the actions of their companies so long as they are profitable;
b) An absolutism in the inviolability of private land ownership, no matter when or how the land was acquired or how large the estate. Even though land is of limited supply and is required by all to live. Hence we have libertarians who advocate "flat taxes" or sales taxes both of which punish human activity, but are offended by the possibility that they pay rent to the community for the privilege of excluding people from their land. Exclusive control of land is a form of monopoly that is endorsed by many libertarians.
