Alcohol consumption, watching porn, gambling.etc are personal preferences. The governments should stay out of this. Gone are the days when the authorities could dictate each and every aspect of our personal lives. If someone wants to gamble, then let him do that. Why the government wants to prevent that, as long as no manipulation or tax evasion is involved? By imposing these stupid bans, the governments are making themselves a laughing stock. Recently India imposed a ban on porn. Can you believe it? Now Indians need to purchase a VPN in order to access porn sites. And from what I have heard, the porn consumption in India went up after the ban was imposed. Same with gambling as well. Issues with gambling addiction are more common in countries where it is officially banned.
When people often access things like that and get prohibited from accessing those things, people will search for a way to help them access, even if they need to purchase a VPN that can make them access the sites. Maybe the government does that because they do not want to see their people will busy with unnecessary things or the government have another reason why they block that. We can guess their reason, but we do not know the truth.
But here we are not talking about illegal casinos operating in a smaller capacity or online gambling, the issue stated acknowledges casinos that have more of a tourist attraction vibe to it than anything else. So those types of gambling are not under the table, are widely recognized and accepted by the state. A completely different subject to just gambling on the internet
Maybe it could be accepted by the state if all sides agree to allow gambling in that country. But if the state is prohibited, people who play traditional gambling or often play on the casino, whether legal or illegal, will try to search for the other way to play gambling still. The state will not allow the casino to operate in their country. If you read more on that article, Dubai's police launch an app where people can report suspicious activity. So it is clear that gambling is not allowed in that country.
People who play gambling will use the hidden place to play gambling without anyone knows and even they will play online gambling, which they can access from their gadget.
