We tried that and it didn't work
And can you tell me why it didn't work?
In my opinion, the main reason was that the people didn't want it.
Plus, it wasn't really enforced (or enforceable) -- the speakeasies were a testament to that. The wording of the 18th Amendment banned the manufacture and sale of intoxicating liquors, but not the possession, consumption, or transportation.
"Cleveland had 1,200 legal bars in 1919, a year before Prohibition went into effect. By 1923, the city had an estimated 3,000 illegal speakeasies, along with 10,000 stills."
