“cheating on marriage with a prostitute is OK” is Bad News. You’re looking at hyperpatriarchy there - the mortal consequences of it might be more… “contained” than either the anarchy we have today or the polygamy you attack, but it’s still very much not *good* even if you think mankind can permit adultery ever which it can’t.
Well, that’s Futurist Shitposting instincts - i.e., I proposed that combination because I find it hilarious, and also culture-shocking and weird relative to today, but feasible for a regime which is socially conservative in pragmatic synthesis ways, yet having retained a touch of the social liberalism of our time.
On the other hand, there are arguments to be made for it.
…which you’re already aware of, judging by what you just wrote there.
