I agree it's primarily cultural. I wonder whether there's anything that a non-totalitarian government can do that would significantly change the cultural side of it.
it is however one of those "stick" things both totalitarian and non-totalitarian countries will inevitably attempt at some point in near future, now that it's clear that none of the "carrot" things make any fucking difference. likely not with outright bans, not even in China, but by artificially limiting availability and raising prices of condoms and pills with tax. like the rest of those things, it will predictably have little to no positive effect.
