I don't really find comparisons to alcohol that useful tbh.
The basic differernce is that while cannabis is simply a drug that people take to change their perceptions, alcohol, although it can be used as a drug, is also a food, and can be and often is used as such.
Historically alcohol products were primarily a means of preserving harvested fruits, grains, and other vegetation for human use - you can pick grapes, or corn, and they will only be good for so long. Ferment them and they will last longer and also have some advantages over water where contamination is a factor. In the middle ages for example quite a lot of people's daily intake of beer accounted for a good portion of their caloric intake.
If you distil the products like wine or grain liquor, you are then preserving all those calories in a very small amount of space that will last indefinitely, so your extra harvest will not be lost to rot, mold, or mice.
The amount of available product in the past was kept in check because of the limits or agriculture and production. It was the industrialisation of the production processes that led to the easy availability of strong cheap booze, and that has of course been a problem for many people.
However, I don't think that changes the fundamental fact that alcohol is a food product as much as a drug.
