"We presently regulate or outright prohibit the sale of booze or ethyl alcohol products approaching 200 proof..."

Well since 200 proof is 100 percent alcohol, I HOPE no one is selling more than 100 percent alcohol. 

And 200 percent alcohol is a pretty effective poison that has killed many many people,  old and young alike.  Banning it makes perfect sense - even though you can walk into any liquor store and buy a a gallon of Everclear 100% pure grain alcohol right now.

Care to guess how many people have died of marijuana poisoning in the history of the world? Zero.
