If we're going to think that it's for a good cause then the answer is Yes, it is essential. Casinos pays a huge tax to the Government no matter how big or small their bankroll is, that's why if your online gambling site are not making that huge of a bankroll, it's better to shut it down or you'll be arrested by the police. Because if you insisted to regulate your online gambling business by the Government, then you'll be losing your profits and it'll all go to the tax you're going to pay.

The ones that's gonna remain are those big time online gambling sites in Europe. Surely it'll help their country and citizens if their Government will not steal the money (fingers crossed)
