A casino is entirely a creature of government. It's regulated into existence, like a bank. Why would any government entitle an entity to exist, that allows you to siphon an unlimited amount of money out of their locality?
> A casino is entirely a creature of government. It's regulated into existence,
Gambling establishments have existed in some of the places with the weakest governments around. They are not regulated into existence, and are often regulated out of existence.
It's true large casinos are often a consequence of both regulating them out of existence in neighboring areas and creating a high regulatory bar to opening one in the area in question, which minimizes competition. But that's not regulating casinos into existence, it's upregulating size by downregulating number.
