I agree on the purpose of casinos, but I fail to see how it's evil to give people what they want and what they would seek out and do on the black market anyway if it wasn't legal. Just because they're legal doesn't mean that we can't focus on treatment or prevention. Keeping casinos legal removes a lot of the other problems that illegal gambling brings. Basically, by keeping gambling legal the damage that gambling does can be minimized and generally limited to the gambler. Once you make it illegal and bring in the black market, while gambling itself is a victimless crime, the industry that now supports it illegally is not. Same as any other industry that deals with highly addictive things that people have immense desire for.
