Well, we did TRY banning alcohol, but it didn't go that well. We do at least generally attempt to prevent children from consuming alcohol, though.
Should we ban alcohol? I think people should stop drinking it, but in general I don't think the sale of things that may be harmful in some ways should be entirely prohibited, it would just be good if we minimized the amount of potentially harmful ingredients in our general food supply. e.g. if someone wanted to buy/sell Red Dye No. 3 on its own I don't think that would be a big concern.
