Yes, in my opinion there is a good side and a bad side, in some countries gambling are prohibited and the user can even be arrested, on the other hand gambling can help the country's economy to develop and attract tourists, for example Las Vegas
If they only see it that way, other government see it as more than addiction that need to stop and can destroy individual life for long time if they continue playing or gambling. Although that's a self decision not by the government but they want to help them to stop by doing it illegal .
Some of them just want to stop the illegal gambling but still, we know that they want only is the legal gambling with permits and other papers, is this quite fair? Because those illegal gambling does not have tax so the government wants to take down them. Well, I think it's just good because we are preventing illegal but at the same time how about the people who get caught just want to play? Just my thought.
At the end of the day, I will agree with legal gambling because there are a lot of people enjoying this without worrying about lawfulness.
