There is not a single reason for any human to get access to alcohol to drink.
Edit 1:
Just to add the people who say that banning does not work is like saying banning guns does not work because people is going to find a way to get them or like saying we should not have speed limits because it does not prevent people from speeding. (Their opinions does not make sense to me)
How would you ban alcohol without repeating all the problems when they tried it in the USA in the early 20th century?
Widespread smuggling caused massive crime because it turns out making it illegal doesn’t make people want to stop drinking.
