I wrote that previous functioning civilizations purposefully restricted male sexuality, enabled utilizing energy that would be otherwise evaporated by sex into building society and its civilization structures instead. So that might be intent of some groups pushing these changes. Other groups might be pushing it for moral reasons, but those rarely had any tangible effects.
Whether you like it or not, it is politically incorrect or going against the Zeitgeist, males still do most of the difficult, manual work that keeps the world running and is invisible to most women. There is a very little hope females would step up to the challenge as what we see so far is cherry picking high-income jobs isolated from crushing challenges of manual work and heavy robotics is not there yet. So if you tell those males they aren't desirable, they can't be entitled to have a partner, you allow them free access to cheap sex/sensory satisfaction, gaming etc. what you'll get is they just wouldn't care about work anymore, live minimalist lifestyles, working only to pay their immediate expenses, your society will be on a path to decline. By removing this "carrot" of a desirable woman, you neutered one of primary motivations of males to do anything at all. As they see 5% top guys getting all the girls and girls being fine with it during their desirable ages, and being interested in them only when their desirability wanes, and that only for financial reasons, why would they even bother being involved with society? So they simply drop out, do whatever they like, don't contribute to taxes, don't do any menial work, refuse to be slaves and disengage from society. I see it on my cousin, who was a top graduate of the most prestigious university of my country, and since graduation he is not working (a few years already), disgusted by women, and playing some stupid online games all day, without any way to poke him to do anything at all as it all seems pointless to him.
So please keep closing your eyes, let's have another completely lost generation and see how our civilization tanks in front of our eyes.
I would suggest you to study reinforcement learning, which even if using really stupid models, could show you how small changes in rewards can completely reshape environments, not mentioning complete removal of rewards, as is happening these days.
