I don't think so, investors have the capital in order to afford to deal with regulations. Over regulating and making it expensive/hard to gamble legally, would just send people over to organised crime. I'd be happy if we forced gambling companies to hire addiction-psychologists in each of their shops for people to talk to, for one we could shrink the amout of gambling shops, as they wouldn't open one every 10 meters, and we would bring help directly to those who need it on the spot
