There is nothing wrong with banning gambling in the country, but I do not believe it would solve the country's problems. Because gambling does not concern the country because the government does not generate revenue from it, even if they ban it, I do not believe there will be any changes in the country, as the word gambling refers to us adults who have no money and use it to reduce the cost of living because there are a lack of jobs in some countries.
Banning would just lead to black market or underground gambling. And since gambling has been with the humanity ever since, I don't think the government can stop such activity from happening. So it would be better to address the tax regulations and other protocols related to it rather than banning this activity. It would create more illegal activities and so the government has no upper hand on it.
Create or develop solid protocols relating to gambling where they can get revenue out of it. In my opinion, that would be a better route rather than totally banning this activity.
