I had no intention of this this becoming a legalize everything thread, but I will chime in on one thought.
To the legalize everything folks, who want to use alcohol as their justification.
I think you are missing what was the actual objective.
Before prohibition, alcohol was freely sold, and was untaxed.
After prohibition the government immediately taxed it, and any other "vices" they could. From tobacco, to gambling, eliminating, and later legalizing things people want is not about any holier than thou ideals. It always becomes about the Money.
If you doubt this look at Colorado and Kali and the taxing of Pot.
The Government NEVER gave anybody anything. It's always about how a petty beauracrat can tax and control you.
