Card counting is not cheating, and is not much of a threat. It is, however, disruptive to their business, which is taking money from suckers. They pay dealers to rake in money, not shuffle and switch decks.

They could end card counting if they shuffled the decks more often, but doing so would mean less time taking money from suckers and bad card counters.
