The valid reason gamblers has to continue gambling is the benefits they drive from gambling. Most of the gamblers are in gambling not because of the money in it but because of the funs and mind development. I think we should allow the gamblers to do what they like to do.
I hope they know what they do in the gambling games and realize before it's too late. I think gambling has a strong poison that will attract people to play more and more because of the fun. People itself playing many games in gambling games, thinking that they can win some money because they hope that they have luck on that day. But when they realize the situation, they will still lose the money no matter how big their money.
