There are many people who can gamble responsibly and enjoy it. I love playing poker, and play in a tournament every few years. Lots of people are compulsive gamblers, though, and lose it all.
Do I have to give up my hobby because some people can’t handle it?
What about drinking? I enjoy a happy hour once a month or so, and have a couple of drinks when I do. Others drink 10+ drinks a month. Do we ban it because of the people who can’t stop? (We know how well that works)
I am not saying we do nothing, but I don’t think it is as easy as “just pass legislation”
