Bluntly society exists to serve current and future generations. All future generations are predicated on a nuclear family. No significantly large human cultures without a basis around a nuclear family have survived from an evolutionary perspective.

For society to continue to exist it needs to primarily serve and be determined by people who meet, have kids, and form a nuclear family. While there are societies that do not do this they do not last more than a generation or two at the most.

While good societies should be inclusive and welcoming of non paired or alternative lifestyles they by definition need to remain alternative for society to continue to flourish or else the society dies as its members do.

We already have a birth rate below replacement rate. Societies where that is the trend typically do not last long either and have some fairly bad outcomes while they disappear.
