The lack of a clear ideological position or philosophy in Libertarianism provides perfect cover for all sorts of extremists, from fascists to Marxists (Noam Chomsky once described himself as a "Libertarian Socialist").

Libertarianism most resembles the 19th century ideology known as Anarchism, as espoused by Elisee Reclus, Pyotr Kropotkin and many others. Anarchists did not actually believe in Anarchy, they were simply opposed to all hierarchical forms of government and business. They had no problem with people owning personal property, such as clothes or houses, but felt ownership of the means of production had to be administered publicly. They recognized that humans were social animals and needed to organize to do anything collectively, you need workers and bosses; they simply argued that all collectives should be democratically run. Governments and corporations might be necessary, but they should be structured by free elections in which all the employees/citizens could participate on an equal basis, as voters, officers or leaders.

Libertarians certainly demand that structure in government, but prefer the traditional ownership model for business. Basically, a Libertarian is an Anarchist who wants to own a business and boss his employees around.
