As this thread demonstrates too well there is no debating a belief system that like communism or socialism are idealized versions of a political and social system. Libertarians believe, same as the communist or socialist or whatever believe. How much for instance is too much regulation, or how big should government be, or what does freedom mean when you cannot find a decent job. In the end there is no simple answer and libertarianism offers none either. Vague pronouncements about freedom are meaningless outside of social reality.

A few more links for the doubters:
"Libertarians believe, therefore, that we are singularly inept as a group. Assuming for a moment that the proposition is true-- there is a lot of evidence for it --
a cynic would propose that the reason we are collectively incompetent is that we are individually incompetent as well....Libertarians, however, are optimists. I cannot fault them for this; I have written elsewhere about the importance of optimism in any human scheme, even to the point of self-deception. Nonetheless, libertarians assume, as most people do, that there is a way out of any given dilemma; their self-deception may consist of believing that what we cannot accomplish collectively, we can more effectively do individually."
Why I Am Not a Libertarian
"The values of libertarianism can not be rationally grounded. It is a system of belief, a 'worldview'. If you are a libertarian, then there is no point in reading any further. There is no attempt here to convert you: your belief is simply rejected. The rejection is comprehensive, meaning that all the starting points of libertarian argument (premises) are also rejected. There is no shared ground from which to conduct an argument...The libertarian belief system includes the values listed in this section, which are affirmed by most libertarians. Certainly, no libertarian rejects them all..."
Why is libertarianism wrong?
"Libertarianism is a philosophy of individual freedom. Or so its adherents claim. But with their single-minded defense of the rights of property and contract,
libertarians cannot come to grips with the systemic denial of freedom in private regimes of power, particularly the workplace. When they do try to address that unfreedom, as a group of academic libertarians calling themselves “Bleeding Heart Libertarians” have done in recent months, they wind up traveling down one of two paths: Either they give up their exclusive focus on the state and become something like garden-variety liberals or they reveal that they are not the defenders of freedom they claim to be."
