When many people get addicted to gambling, that will become a serious matter to the government because it can trigger another problem. The level of crime can also increase, so the government should think much about that.
In reality, the government has nothing to do with that. The post-gambling effect is a behavior that only a gambler knows.
Crime related to gambling can't be controlled by the government no matter how strict the regulation is.
What the government's concern is illegal gambling operators and that's a big problem compared to that gambling behavior related stuff.
