There is also a ridiculous law that you can't use math at blackjack tables.
Not true. There is no law (in the US) forbidding card counting. However casinos will kick you out (or most likely politely ask if you might want to play something else) if they believe you're counting cards effectively (they have no problem with people who count cards badly). But this has no basis in law and isn't an accusation of cheating. It's just the casino exercising their right to remove anybody from the casino floor for any reason they feel like, much like they have the right to remove you from the casino floor if they don't like the way you're dressed for example.
Its like only stupid people can play blackjack and if you are clever enough to beat it, then you are cheating.
Put simply according to them the game is fair only if you lose and casino wins.
