There are a lot of things that can be done to limit alcohol without outright prohibition that may be worth exploring. An example is what has been done with smoking.

1. Ban all alcohol advertisements. There is a ton of advertising that normalizes and glamorizes alcohol use.

2. Ban alcohol sales at large public venues like stadiums, concerts, etc.

3. Require companies to ban alcohol at all company sponsored events.

Doing these things would greatly cut down on alcohol use, while not prohibiting it and running into issues at Prohibition.
