My point is: due to the natural curve of population growth there will always be more younger, potentially frustrated men who lack opportunity. Your only realistic hope will be to convince enough of them to help you police the subset who refuse to be convinced.
How do you influence them? What do you bribe them with?
Even the high clearance rate in places like Japan is suspect. So it seems like a problem, but it seems universal.
The point of this is that the civility of society is, for better and for worse, not upheld by enforcement - but by an unspoken agreement to a social contract. If any remotely sizable group of people chose to break that agreement, it would be unpleasant times ahead. Even this issue aside, it seems self evident that trying to run a society through coercion would be unstable at best.

Sometimes unpleasant times are necessary in the fight for human rights. Otherwise we would still have things like slavery. Additionally, women wouldn't have the right to vote, and they also wouldn't be able to make independent financial decisions like have their own bank accounts or mortgages. These things aren't that historic, and taking the side of trying to restrict women's relationship choices strikes me as being on the wrong side of history again.
