Procreation at this stage of our civilization is not the hurdle, procreating high-value citizens is the hurdle. Whether your value metric is happiness, ethics, wealth, income, etc., or whatever combination.
Once past the baseline survival of struggling to meet and secure basic physiological needs, arguably established for the majority in the developed nations, our species (not just "the state" groupings) should be blind to which groupings (not just pairings) facilitate the procreation and raising of high-value future adults, and if interfering at all, should instead focus upon which individual "family" groups are producing high-value results, regardless of the structure of the "family".
There are long and interesting discussions about what constitutes high-value; that's politics. But I don't subscribe to the notion that there is a currently-valid "objective interest" in promoting heterosexual families on the basis of straight-out procreation. If the species dropped to a population bottleneck level again, then sure; but absent similar catastrophic situations, I don't see where simply promoting procreation progresses the species' civilization, though I welcome counter-views.
