A "dry" county only means they don't sell it there. You can buy it elsewhere and bring it home.
"This should at most be done at the local level by city councels"
Would that work?
Let's even bump it up to the state level. If 5 states legalized cocaine, would that present a problem to the other 45? Would cocaine be smuggled from the "wet" states to the "dry" states, making it next to impossible to enforce?
Prior to Prohibition, about half the states banned alcohol at the state level. That didn't work too well, since alcohol was being smuggled. The federal government passed the Webb-Kenyon Act making the interstate transportation of alcohol illegal. That didn't work either. Finally, Prohibition was passed.
What didn't work for alcohol will work for easily concealed drugs like cocaine or heroin or meth? Let's not kid ourselves.
Yep, prohibition didn't work then, and it doesn't work now.
What didn’t work for alcohol will work for easily concealed drugs like cocaine or heroin or meth? Let’s not kid ourselves.
You should read your own words. You’ve nailed my whole argument in a nut shell. What didn’t work for alcohol hasn’t worked for drugs like cocaine, or heroin or meth or pot, i.e. prohibition.
