Society is a complex machine designed by a long period of social evolution, and if you make random changes to complex machines it might improve but it will probably stop working. Traditional society is tried and tested. Changes may seem appealing for various reasons, but then a few generations down the line society collapses for unforeseen reasons. Note this doesn't really hold if society is adapting to technology - even if patriarchy were best for a medieval society where the superior physical strength of men is important, it doesn't necessarily hold for the modern world with a knowledge and machine based economy.

Yes, as Nick Szabo explains in his essay on objective versus intersubjective truth:

In some cases and for some aspects of tradition, a radical shift of technology, such as moving the institutions of law and governance from paper to computational/networked multimedia, or the medical technologies of life extension, demand radical (in other words, shallow) adaptation of interpersonal traditions. This despite our profound inability to predict consequences or find the long-term good solutions over the span of a mere few decades, within which technologies can so substantially change the nature of our relationships. Choose your poison.
