The town of Street in Somerset is an example of what happens when you ban alcohol. As the Clark family (of shoe fame, Street being Clark Central for a century or more) did. All the pubs are around the town, as one example, they not allowing any in town on the land they owned.
But more than that, with no alcohol to dim the urge to do crazed things (as opposed to increasing the urge to think up crazed things) we end up with the random latin hexameter generator.
No, alcohol truly does have its place in a civilised society.
