True to your character you took one sentence and twisted it out of context. Then go on to construct a straw man around that. A disingenuous one at that.
The first thing civilization must have is a sound, intact, healthy family structure for the rearing of children.
Okay, I'll play your game, but just this once. The second thing civilization and the family needs (I mean, how hard can it be to make love and conceive a child. I suppose you'll want to argue that government is needed to referee that too.) is business/science. It's especially useful for the family members to be healthy and lead creative productive lives.
I'll skip resending to your below rant. ...And rant it is.
I cannot easily understand why so many libertarians believe civilization can be had on the cheap, by paying mere lip service to families. In their cramped minds civilization somehow blossoms forth spontaneously from an ether of dope, nonchalant sex, booze, porn, and adult ocnceits. The value of families lies obscured by a libertarian "me first, best, and only" lacuna.
Watching a libertarian grapple with the concept of family is akin to watching an old Star Trek episode in which Spock struggles to understand the nature of human emotion.
