Meaningless sex? Is that sex where you cut it off just before you both come, and sit on either bedside, with the backs towards each other for five minutes, then just leave?
Because sex that is enjoyable, pleasurable for all involved is never meaningless.
If YOU spread resistant strains of STD, YOU are to blame, dumbass!
A much better way to fulfill the depopulation requirement (not agenda; we HAVE to do it, or we will breed ourselves into extinction), is to teach kids safe sex, and provide them with affordable or free contraceptives, thereby reducing the number of unwanted pregnancies significantly. Vasectomies and tube-tying should also be easily available and affordable, for people who feel they’ve already had the number of kids they want, but still want to have bonding sex with their partners.
Perhaps also make MEN responsible for the care and upbringing of children, not just women. Find the dead-beat dads, and force them to be there for the children they have conceived. That might make some men think twice before they spill their little swimmers indiscriminately. (Abusive men (nor abusive women) should of course not be put in charge of children.)
