I already explained how the law could enforced, seriously, in my otherwise semi-satirical* post preceding the last one, You can harness AI technology, which we have, to monitor sound coming from people’s houses, which can be monitored by aiming lasers at their windows and affixing motion sensors to their rooftop ventillation. Throw in pervasive CCTV and you have the high tech solution.
Alternately just do what the DDR did and make 1/4th of the population informants.
*The term from the Jargon File as maintained by Eric S.

My presence with you now is a product of wireless keyboards).
As an aside, I think I got chatgpt 4 to do an improved image of the propaganda poster for my proposed utopian society, so for your collective enjoyment:

Now I think I might well derive some enjoyment from living in such a futuristic society, but I imagine other members of the forum would find such a brave new world where sex is limited to the married and those who violate the law turned into slave labor to be more of a dystopia. However given my relative lack of sympathy for adulterers, it is pleasurable to imagine what could be accomplished if they were put to a more productive use for the rest of us.
