Just like you I think it's a good thing that VPN is not allowed to some well known casino to reduce or to eliminate the possible effects of gambling addiction but it all boils down to the addicted gambler. An addicted person will find a way to continue their vices even if it mean to gamble on a physical casino that operates illegally.
Furthermore, I think an addicted individuals will try to find some alternatives even bypassing VPN restrictions and it's not that difficult these days with booming technologies.
VPN are not acceptable by gambling sites, it's always introduced in their terms and conditions because these VPNs have their various negative effects towards online gambling accounts. Wagering online will fasten the entire process because online gambling happens to be one of the very best techniques that a gambler can easily earned from the comfort of one's home without any intervention of the third party. Gambling ban in most countries, is a beneficial option for the citizens because the government have just save them from the hands of gambling. Still yet, alot of people argued and are interested in gambling by all means.
They're prohibited but if the casino itself doesn't finds it out that some individuals are using it, they'll continue on it of course. There are cases that even if gambling ban is ruling in the country there are even more illegal gambling activities that happens because of it, it may be beneficial to citizens but the government will find it hard to cope with in real life scenarios.
