Perfect i agree, but why stop there, why don't we ban gay sex altogether, i mean if we ban saunas they will just change the venue.
Fair question. You could argue that closing the saunas wouldn't turn gay men asexual... it would just surface somewhere else unregulated and particularly more harmful.
But that's not entirely how that played out -- at least from my impressions. If anything, there were a lot of reckless fook-ass-til-I-die people among gays who would not be changed. But the shift made people more cautious and took precautionary measures more seriously. Probably saving a number of lives, but you really can't prove that scientifically without tests that would ring a number of Nazi-adjacent ethical alarm bells.
Should that mean we don't try anything on the chance of getting it wrong? That's where I disagree. Governments and public agencies are known for not innovating crap for the most part. But that has to do more with a standard of failure that is allowed for private businesses but not for governments.
I think we need to encourage state actors to take more safe-to-fail gambles to learn from, because a lot of this crap is too complicated to successfully model in a lab and thinking behavior might lean one way doesn't make it so in action. That means citizens need to allow programs to try and fail in the interest of learning more for the next attempt. Instead, there is such a hostility to failure that nobody takes reasonable risks.
