The problem is that "consent" isn't a binary, it's on a continuum. When people are bombarded nonstop with advertising for video gambling, eventually some of them will take the bait. And those who do will be the ones more susceptible to the inherent lure of gambling, and as such the ones most likely to be addicted to it.
sure. On the flip side, few years ago I went to a casino in Rosemont, had a good time, ate a steak, played a few games and went home. And I am not addicted to anything and don't want it closed. 20% of people who drink alcohol get addicted. Should we close every bar in Chicago?
The straw man of banning gambling everywhere is not what this is about. Sure, consenting adults should be able to indulge in vices, but we should regulate them to reduce the social harm they cause.
