Is the distribution of sex in liberal societies problematic?

Consider this quotation:

. . . in societies like ours sex truly represents a second system of differentiation, completely independent of money; and as a system of differentiation, it functions just as mercilessly. . . . Just like unrestrained economic liberalism, and for similar reasons, sexual liberalism produces phenomena of absolute pauperization. Some men make love every day; others five or six times in their life, or never. . . . It’s what’s known as “the law of the market.” In an economic system where unfair dismissal is prohibited, every person more or less manages to find their place. In a sexual system where adultery is prohibited, every person more or less manages to find their bed mate. In a totally liberal economic system certain people accumulate considerable fortunes; others stagnate in unemployment and misery. In a totally liberal sexual system certain people have a varied and exciting erotic life; others are reduced to masturbation and solitude.
—Michel Houllebecq (source)

Is he right? If so, is this a bug or a feature? If it’s a dysfunction, could the uneven distribution of sex be causally connected to other dysfunctions in liberal society?
