Honestly, i feel like there is a lot of sarcastic tones in these threads... so pardon my ignorance if i miss any obvious wit.
With that said, i've always liked the idea of reversible sterilization as a standard. It is of course a worrisome proposition to suggest we forcefully sterilize people.. which i'm not exactly saying. I'm simply saying, what an interesting world would it be if reproduction was never by accident, and always intended.
