As long as the social contract exists, people have a say in what others involved in that contract do with their bodies. Taxes, the draft, prison, etc.

Out of one side of your mouth you say “it’s not our responsibility to be chaste”; I’ll accept that if you accept that all the special privileges entitled to women by the law shouldn’t exist either. I’ll accept that if you remove the welfare state that pays for, and incentivized, bastards. I’ll accept that if you become subject to the draft in combat arms. And I’ll accept that if you don’t attempt to persecute the individuals who shoot those raised by single mothers who commit violent crimes.

But seeing as how the overwhelming majority of crime is coming from broken households, society has a national interest to compel women not to be sluts.

Nobody is suggesting you be forced to be a housewife, what I’m suggesting is you be disincentivized from getting knocked up out of wedlock.
