Based on what we now know about the health effects of alcohol, I think if alcohol was "invented" today there's no way it would be legal, we just have a 10,000 year long status quo bias.
Are they going to make grape juice illegal, too?
Prohibition tried to ban booze, and it failed for those reasons.
I see it as a good reason to legalize things invented recently rather than making alcohol illegal. The prohibition and the war on drugs should have taught people something.
