> Instead of aggressively diminishing this opinion with whataboutisms, legalizing proponents motivated enough to answer to this person should IMO better take into consideration (and respect) this opinion.

Regarding the US: We already experimented with alcohol prohibition. It failed for the same reasons that marijuana prohibition failed. (I believe Europe did the same thing, but I'm less familiar with its history.)

You're advocating for a "nanny state" law. These are difficult in democracies.

In the US, we see debates about similar issues: Some people want to ban guns, some people want to ban abortion, some people want to ban bad drivers, some people want to require helmets for XXX.

Nanny state laws only pass in the US when the politicians who pass them know they will get re-elected. (IE, the US has some areas with very restrictive alcohol laws, because the people in that area believe drinking is a sin.)
