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 .
