It's also extremely simple to produce enough alcohol for your entire neighborhood in your basement with a home-made still.
That has not stopped the monetization of alcohol...
People who want to make billions from this will simply lobby until there are extremely strict laws in place to protect their profits, and then also lobby to make sure there are wars and extremely strict punishments for violators of those laws.
Even the easiest homebrewing requires more knowledge and skill than dumping some seeds in your garden, which is literally all you need to do to get an acceptable crop of weed
Acceptable certainly is relative. If you just "dumped some seeds in your garden", you would get seedy, low-grade crap weed, regardless of what strain you planted. Good weed requires proper attention and care.
In my experience, as long as you select the right seeds/strain (feminized seeds are readily available) and harvest in time, you won't have "low grade crap weed"(obviously that description is subjective) but a very marketable product. Yeild is more difficult to optimize for.
Since other people are comparing rudimentary horticulture to consumable alcohol production for some reason, making market grade alcohol is not nearly as simple. Aside from maybe some parts of West Virginia, basement hooch is not in high demand.
Also, it's much more labor and processing time intensive. It's not true that alcohol demand can be satifsfied in anywhere near similar space and labor requirements that marijuana demand can be.
Plus there's the risk factor. If you fuck up distillation of alcohol, even slightly, people may die.
You get the temperature control on your distillation wrong by 3 degrees, people will get sick from drinking it. 5 degrees, and it may kill kids who happen to get a hold of it, and starting at about 8 degrees it gets to the point where 2-3 glasses of your homebrew whiskey will kill a full blown adult.
I know that home distillation of https://en.wikipedia.org/wiki/%C8%9Auic%C4%83 is still fairly common in Romania for example, and you don't see many people dieing. It can't be as hard you think.
In Romania, while many rural families leave a barrel of their own plums, apples, apricots, etc. to ferment, they usually take the fermented fruit to a central village distillery to distill it. The men working there have long years of experience and know how to run the equipment. I have always found copper stills to be "as hard as you think"; I couldn't imagine ever trying to set one up in my own home.
The most common liquor in West Africa is palm wine, which is not distilled and so methanol does not form. However, West African countries fairly regularly see cases of drinkers going blind from homemade distilled beverages, I would be very cautious about the provenance of any strong liquor offered to me.
