I can't say anything else but I can say that just banning gambling is not a guarantee that people will be stopped from gambling.
Rather, if I say that gambling is banned in my country, I can still gamble. However, this is normal, even though gambling is banned in my country, even underage school children here gamble in online casinos. So I think just gambling is not enough.
It won't guarantee to solve the addiction problem of people if they're going to ban it. It will somehow retaliate still to what they've decided with.
Some gamblers might be discouraged with that and might just do some other things aside from gambling.
But the real gamblers will still be committed in finding some areas where they can gamble, physically or online.
