I am skeptical of your don't-bother-regulating-because-it-has-no-effect arguments. Cigarette usage in the world, for example, seems to correlate well with how unfettered commercial suppliers are. Everything we know about retail says that convenience and marketing impact sales. Advertising works, or companies wouldn't buy ads. Premium shelf placement works or retailers wouldn't study it to death. Getting people hooked works or pushers at every level wouldn't bother. Addiction to hard drugs (e.g. opioids) is a huge ball of misery and human suffering. It bothers me that you shrug that off so easily.
