So, there are these things called candy cigarettes. They are candy shaped like cigarettes. Despite simply being things like bubble gum or chocolate, it turns out that people who ate them as kids are about twice as likely to smoke real cigarettes as adults. This has resulted in them being banned as advertising tobacco products to children in a good number of countries. This add for nonalcoholic beer specifically saying that minors can buy it can easily be argued to be the same kind of thing, with the same kind of legal response. If consuming non-alcoholic beer as a minor results in significantly higher rates of alcohol consumption as an adult, then ads for non-alcoholic beer that target children, like the one shown, might be worth a ban.
