Gambling will not be banned, even if all the governments of the world insist on doing so, gamblers will find all kinds of ways to keep gambling. If we look at the history of the players out there, there are those who are happy because of gambling, but there are also those who are suffering because of gambling.
I think regulating gambling is a good thing, but the government that feels the money from gambling taxes should provide rehabilitation centers for those who suffer from gambling (addicts).
The government can ban gambling, which has already happened in some countries for religious reasons. But those who are used to gambling will surely be able to return to gambling even in places unknown to the government.
Maybe only regulating gambling can be done by the government and making strict regulations and gamblers must be willing to be monitored by the government. This is for the good of the gamblers so that they do not cause other problems in the future because gambling can really make them addicted. But if some gamblers become addicted, the government should be able to find a solution and maybe providing a rehabilitation center is one way to help them.
Government can ban gambling which has already been done on some countries however gambling cannot or rather will not be banned on all countries. Gambling has been one of the industries that provides a lot to the government and some might even rely on it.
Also, enforcing strict regulations especially monitoring gamblers with their gambling activity is not a concern that the government needs to look at. I mean, it's not the government decision whether or not the gamblers activity will cause a problem or not as various aspects will need to be look into. Gambling addiction is not a job for the government but rather it's for the gambler to get checked at a psychiatrist.
