We all know sugar and processed food is bad for us but obesity is rocketing. We have to get away from "personal education and responsibility is the answer", because while correct to actually a pretty decent extent it's plainly not sufficient at a societal level and across domains such as diet, investing, gambling, smoking, drinking, etc.

"Place limits on availability of toxic stuff" is a better answer IMO, albeit again not perfect (see abuse of illegal drugs).

But yeah, unchecked promotion of gambling is really not good and should absolutely be curbed.
