Where does libertarianism demand moral responsibility?
In reality. If there were no consequences for immorality, there would be no need for morality.
Morality is not some arbitrary code of behavior; it is distilled wisdom from God, and from generations of our ancestors who learned the hard way just what was and was not a good idea. It is a rule of thumb that one can use to judge his actions and the likelihood of bad results, even if he is not experienced enough to fully appreciate the full ramifications of his actions. This is why it is useful to teach children morality, and why our society, that has turned away from such things, is in such a mess today.
There are, unfortunately, many who never graduate from 'morality as rules' to 'morality as wisdom'. Some continue to keep the childish view of things as adults, and fall into two categories: tattletales and brats.
Tattletales have not embraced the reasoning behind their morality, they simply obey, and feel compelled to force others to do so, as well. The problem with this, however, is that tattletales cannot fully embrace morality. All of the pieces do not fit together if we try to cram in the notion that we can compel others to behave morally. For example, it is, IMO, immoral to practice violence against someone simply for being foolish, and yet this is precisely what, say, the Drug War does.
On the other hand, we have the brats, who refuse to admit that the countless generations of humanity who have come before them, much less God, might possibly have answers to common human problems. As is typical amongst juveniles, they know everything there is to know. They also see the tattletales deliberately behaving immorally in the name of morality, point to such, and declare morality to be bunk. And then they end up spending years of their lives regretting their stupidity, assuming they even live that long.
I do not understand why so many who call themselves moral cannot appreciate the morality of forbearance. Morality, in the end, is wisdom. One cannot beat wisdom into a man; it is something he must acquire for himself. Attempting to do so will simply make him hate you and everything you stand for, and give him all the more motivation to defy you when your back is turned.
Reality _is_ morality.
