As far as I can see, a card counter is still subject to the same mechanic as any other players, but they are able to perform better then most people within these confines. So why is card counting a justification for casinos to kick people out? Obviously, a card counter will cost them money, but if that is the only justification, then it's like the casino is cheating- they only allow sucky players to play. If you are too good you get thrown out. Is that all there is to it, or is there a valid gameplay justification for this?
