There are some fatal flaws in the liberatarian position:
Libertarians take little account of market externalities, both positive and negative.
Libertarians do not seem to understand that it is often in one's rational self-interest to care for the common interest.
Libertarians take a naive view of human nature, often not taking into account the consequences of the concentration of power in the hands of a few.
Libertarians are often two-dimensional in their rationality, not acknowledging the negative ripple effects that unrestricted laissez-faire brings.
In short, hyper-libertarianism sounds good on paper. Kind of like communism in that respect.
And there are other things as well. And, Terry, you do come across as very dogmatic. People can see that pretty clearly, dude.
