Well,
gambling = more money/attention
fantasy = more money/attention
The combination of the two, just deemed legal anywhere, is just more money on top of more money. If I had dollars to invest in something, it's only a matter of time before there's sports betting kiosks or something in every shopping mall. Yes, I'm aware everything is going/already digital and an app on a phone, but the biggest gamblers are the poor, and they lag behind when it comes to expensive tech stuff. The people who still go to malls would be spending money at a convenient, physical place to gamble freely.
