The main problem the vast majority of policy proposals for this sort of problem face is that the proposals almost invariably slip in the idea of some sort of human being, if not an entire population of humans, that is abstractly above the problem and can be trusted to administer the policy. But if that was the case, we often wouldn't have the problem in the first place.

It's really hard to policy-fix something that literally 99% of the population is doing. Who is going to propose it? Who is going to enforce it? Who is going to pay attention to it?

And to be clear, this is commiseration with you, not argument. I have no solution even in principle.

I agree with you. I feel like it becomes the nebulous question of, "how do you change a culture?"

Honestly I think part of that historically came from "shame", but that's certainly out of fashion these days, plus people can just go to their social media bubble to escape it.

I'm starting to think religion was a useful ingredient too: "because God said so" has its uses. "God doesn't want you to mix fabrics, eat pork, or use social media"
