Libertarian thinking is for the most part, jungle mentality thinking. The law of the jungle, mindless evolution, and selfishness are dominant.
There has never been a libertarian Utopian society.
Why is that?
Because human nature would not allow it.
It is human nature to act on animal instinct.
It is the higher reasoning faculty which is able to evolve beyond the animal instinct.
In every culture we have ever seen, we have seen power wielded by the strong over the weak for the benefit of the strong...not for the benefit of the society as a whole.
Our framers were a rare breed, to a great extent because they were influence by the leading philosophers of their day, who argued for the good of the society as being more important in the long run than the good of an individual.
Look, the Paulites could buy some country (or actually all move to Paulville Texas http://en.wikipedia.org/wiki/Paulville,_Texas ) and show the world how well their philosophy works in practice.
Of course that will never happen...
If we put the ideal of the 60's of communal living on one end of the spectrum, and the Libertarian ideal on the other end, it is easy to see that neither extreme would work unless the individual themselves were living a state of Enlightenment.
What works best is a system of checks and balances against abuse of power.
Our system of government is still the best going, and the problem is that the system of checks and balances has been corrupted by the influence of powerful corporations and money.
Why not just fix our own system, which is the best practically designed system, and eliminate all the extremist thinkers who live in the fringe...
I doubt we would find many leaders of the intellectual, philosophical, cultural and moral development of those who founded our government...because our values have shifted dramatically between genuine patriotism and love of country...and selfishness and desire for personal excess at the expense of the society as a whole.
