I don't think banning gambling entirely can be possible most of this casino site are been owned by most these top politician and it's also a major source of income for them and there also poor masses benefiting from gambling some citizens have been able to put food on their table by getting employed to work in those gambling centers, a country can only put some restrictions that can help reduce the rate of addicted gamblers in countries if they know that rate of gambling is too high and it's also causing more harm than good to it's citizens, but banning gambling entirely won't be possible and it can't also solve any problem.
