Temperance movements and organizations have been around since alcoholic drinks were manufactured at scale. In the 19th century, in the lead up to Prohibition in America, arguments to ban alcohol centered less on the need to morally reform “habitual drunks” and more on the substance itself being the root of evil. “Habitual drunks” were merely those who had submitted to a temptation like any sin because of a flawed human body, but the substance tightened its grip and drove the drinkers to sin. By banning alcohol to take it out of the hands of everyone, the “habitual drunks” could then pursue God from a sober state of mind to repent for falling into temptations.
Prohibition was a disaster, and the policies were quickly rolled back after a great expansion of wealth for organized crime. It turns out that everyday people will still seek alcohol despite what the law says, because people like to drink. Lots of people can drink in a way that doesn’t seriously derail their life or sanity. Even if you lock up a bunch of poor drunks and shut down back-alley breweries, wealthy families will still hold lavish parties with illicit substances that they could easily still procure. The focus after this returned to the drinker rather than the drink.
