So far, seeing that there are only a few casino places that follow the rules of the government, the rest they don't care about the rules given by the government, online gambling is difficult to ask to obey government regulations because they don't have real-world gambling locations so maybe That's one of the thoughts of online gambling place owners.
Maybe the casino that does not follow the government's rules doesn't have a license, so they don't think that following the rule is necessary. But if that is happening like that, maybe that casino will get something bad from the government because they don't follow the rule. I don't know how online gambling can follow the rule because they are not bound by one country. But I am not sure about that.
What if the casino is virtual and how do you propose on taxing them if they are registered and located in a free heaven. It is impossible for them to tax them, all they can do is impose a complete ban of online gambling and encourage gambling houses to register with the government to get the approval to run the site, you know and everyone knows that it is impossible to come with that kind of restrictions.
I think the online casino will search for the country that does not apply any tax for any online business. If they can get it, they will not have to think about the tax, and they will run their business smoothly. If that so, the government needs to make a regulation related to the online casino so they can still get taxes from the gambling business.
