A massive number of society's problems are caused by absent or bad fathers. Imagine if, before a baby was conceived, a man had to consciously think, "I want to have a child with this woman, so I'll come off the pill." Not just "I want to have sex, this woman is willing, and it'll be less enjoyable if we use a condom."
Of course, it wouldn't be a panacea. There would still sadly be men who choose to come off the pill but are bad fathers anyway, or decide once the reality of parenthood sets in that they can't be bothered. And there would also be men who just don't bother to take the pill properly and are then shocked when the woman gets pregnant. But on balance, if there were a way for men to have condom-free sex without potentially having to pay for a child for eighteen years afterwards, a lot of them would be downright religious in their use of it.
I'm genuinely intrigued to see if anyone disagrees with this. I can't see any downside.
