I think you misinterpreted the OP. They weren't saying alcohol should be prohibited. They were saying to watch for the warning signs of alcoholism. I would argue that North America's culture of legal taboo around alcohol is what creates the conditions for the bad alcohol habits OP described. You can't have a drink with your parents at a restaurant, but you can have a clandestine binge drinking party.
