"...Basically, libertarianism works in a world where people are innately good, without any evil impulses anywhere. Sadly to say, that world does not exist."
Of course libertarian ideas won't work without a moral component. That's been said since the beginning of our country, Poohbah.
I'm too tired to lok for it, but paraphrased, a famous quote from those times said,
"Our society is made for a moral, religious people. If the people abandon their morals, our Republic will not survive."Our founders were libertarian, and everybody the world over knew that their "idealistic" government would not survive.
Said component being notably lacking in libertarian philosophy.
