First, cough syrup ID checking is not about deaths, as nearly none are associated with dextromethorphan abuse (17 from 2000-2010, and most not from OTC). But an estimated 980 deaths/year from acetaminophen abuse: https://www.propublica.org/article/tylenol-mcneil-fda-behind...

So that's a great example: harm adults because young people have access to something which is hardly dangerous, but set them free with multi-ton killing machines once they turn 16 years old and let them buy an actually-deadly medicine with no restrictions.

Regulation which says "adults should easily be able to enable client-side child protection settings on retail devices" would be fine. It's not okay for government to make it necessary for LLM providers to verify my identity.
