Those people do not have a gambling problem, though. They are dropping a few bucks a month to buy a daydream. It could be worse, they could be spending 10x that on Starbucks.
What would that look like? Would gamblers have to send copies of their pay stubs or bank statements to every casino or gas station they visit and every gambling app they use? I'd be happy if we focused on restricting the most harmful actions of the companies who profit from the people they turned into addicts. No more online sports betting. No more adverting for gambling. No more targeting children with gambling in video games that accept real money for anything. No more using AI or surveillance to detect and target addicts.
