This comment says a lot more about you than it does about the article or his cause, and it ain't pretty.
Actually, Mr. Sabia missed an important insight here when he notes that the costs of sex have rapidly declined.
Libertarians often define morality in economic terms -- people will or won't do something because of the inherent costs/benefits of a particular course of action.
It's interesting to look at today's social problems through this lens. It explains a lot.
Traditional morality in this view is expensive, because it generally involves the rejection of an immediate pleasure in favor of some longer-term gain -- or sometimes even nothing at all.
Libertarian cries for normalization of various vices (and in this regard, Hollywood and the various media outlets are consummate libertarians) simply raises the perceived cost of moral behavior. Moreover, "the market" richly rewards those who best promote the pursuit of cheap and immediate pleasure.
And libertarians -- you, for instance -- tend to loudly denounce those who object to those market forces. It's enough to make one conclude that a truly libertarian society is inherently unstable.
The only market Libertarians denounce is the one composed of political ideas and the voters that determine their value.
