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)
This article says, in the headline, that it will help tackle underage drinking. So, first, an assertion that the future will be a particular way is not evidence of the claim the assertion makes. Second, in the article there is a statement that banning a particular consumption method reduced consumption of that method. Sure, I’ll grant that, because duh? But do you understand that the United States spent a great deal of money and lives over years to ban alcohol for adults and it simply did not work? We have the data on this, it’s not even a little obscure.
