Answer:
Too Many People Drink
Advocates of marijuana legalization often point to a 2015 Pew Research report that indicated that almost half of all Americans — 49 percent — had tried marijuana. That's roughly the same as the number of Americans age 12 or older who report that they currently drink alcohol. Realistically speaking and in either case, how can you outlaw something that roughly half the population does on a regular basis?
The Alcohol Industry Is Powerful
The Distilled Spirits Council of the United States reports that the alcoholic beverage industry contributed more than $400 billion to the U.S. economy in 2010. It employed more than 3.9 million people. That's a lot of economic muscle. Making alcohol illegal would strike a significant financial blow to the U.S. economy.
Alcohol Is Endorsed by the Christian Tradition
Prohibitionists have historically used religious arguments to ban alcohol, but they've had to fight the Bible to do it. Alcohol production was Jesus' first miracle according to the Gospel of John, and the ceremonial drinking of wine is central to the Eucharist, the oldest and most sacred Christian ceremony. Wine is a symbol in the Christian tradition. Outlawing alcohol would affect the religious beliefs of a good portion of American citizens who are protected by a Constitution that promises freedom of religion.
Alcohol Has an Ancient History
Archaeological evidence suggests that the fermentation of alcoholic beverages is as old as civilization, dating all the way back to ancient China, Mesopotamia, and Egypt. There was never a time in recorded human history when alcohol wasn't part of our experience. That's a lot of tradition to try to overcome.
Alcohol Is Easy to Produce
Alcohol is pretty easy to make. Fermentation is a natural process, and banning the product of natural processes is always tricky. Jailhouse "pruno" can easily be made in cells using products available to prisoners, and much safer, tastier beverages can be made cheaply at home.
As Clarence Darrow put it in his 1924 anti-Prohibition speech:
Even the drastic Volstead Act has not prevented and cannot prevent the use of alcoholic beverages. The acreage of grapes has rapidly increased since it was passed and the price gone up with the demand. The government is afraid to interfere with the farmer's cider. The fruit grower is making money. The dandelion is now the national flower. Everyone who wants alcoholic beverages is fast learning how to make them at home.
In the old days the housewife's education was not complete unless she had learned how to brew. She lost the art because it became cheaper to buy beer. She has lost the art of making bread in the same way, for she can now buy bread at the store. But she can learn to make bread again, for she has already learned to brew. It is evident that no law can now be passed to prevent her. Even should Congress pass such a law, it would be impossible to find enough Prohibition agents to enforce it, or to get the taxes to pay them.
But the best argument in favor of keeping alcohol legal was the precedent set by the Prohibition to which Darrow referred. The Prohibition failed, repealed by the 21st Amendment in 1933.
