I would wager it's because they have much bigger things to worry about than a (comparatively) small population of well-heeled folks who want to go get drunk, gamble, and get laid for a night or two. If it ever becomes a Problem(tm) such that the state feels like they're losing significant sums of revenue, I'd wager there would be a crackdown.
