Sports gambling is the perfect counter to everyone who says "people are going to do xyz anyways so it's better to legalize and tax it". Yes some people will gamble regardless of the legality, but putting the experience in an app in your hand, gamifying it to maximize addiction, blasting ads 24x7, including in the broadcast itself, having all your favorite athletes and celebrities endorse it, getting VC/PE and big corporate involved and giving it wide social acceptance increases the problem 100000x. It's perfectly fine for such vices to be left in society's underbelly rather than shoved in everyone's faces.
