Despite this idea, I don't agree with it.
Yeah, it is a great idea but if we will be thinking about it, don't you think gamblers would just take advantage of these services and don't mind their health when it comes to gambling? Instead of supporting them to gamble their money, we should be doing something that makes them in control of their money that is for the better of their lives.
No insurance companies will provide a service like this since it's uncontrallbleand it's a personal will of the people, I doubt there will be a legal company who will implement such products that can make their company at loss. Maybe those who also own casinos will do that but with too many rules, classification, steps etc and with high premium since it's quite impossible to provide insurance for gambling.
