At the very least, ads should be banned or require nasty images like tobacco products.
Slight tangent, but I am now of the view the state should not be allowed to tax legal vices. (Drugs, gambling, alcohol primarily). The reason is it keeps pushing amazing conflicts of interest, and the state ends up incentivized to maintain the behavior it supposedly does not want.
Either [vice] is wrong and should be illegal, or is tolerated and regulated but in no way profited from by those that do the regulation.
Either gambling is bad or it's not, but in practice people like to be incredibly selective about it, as here, where as you point out sports betting lacks the positive externalities which for some part of the population offset the negative effects.
Having the TV blaring gambling commercials at you constantly and having the ability to place a bet from your phone at a moments notice is completely different. You’re comparing having a glass of wine on a special occasion with downing a fifth of whiskey every night.
