Bars cut off drinkers when they're getting drunk, but casinos allow gambling until you're bankrupt/suicidal?

As Leg said, this is a Q&A forum, and you definitely sound like you want a discussion here. But to comment on one portion of your post: Casinos are definitely able to restrict players gambling amounts if they are asked/forced to. My home state of Missouri enforced a $500 loss limit every 2 hours for 15 years until the casino lobby successfully got that law written off the books. While the loss limit was the law of the state, you had to have a players' card, and had to have it inserted in the machine to deposit money. If you lost $500 in less than 2 hours, your only other option to gamble in Missouri was to drive to another casino. I think it was a great idea, and Missouri was stupid to get rid of it.
