As low as my opinion is of casinos sometimes, the fact remains that they don't force anyone to come in and gamble at their tables or machines. Even though they make sure there's no shortage of alcohol available and would be more than happy to get everyone hammered while their money's on the table, they don't force anyone to drink. If you don't have the self-control to restrain yourself, then you shouldn't be in the casino.
And as much as we may hate it, the casinos also have a right to protect their business from APs. Just as we have the right to play with an advantage for as long as they'll let us. (so long as we're not cheating) If a casino wasn't able to detect an AP and he took the tables for 5 figures, then they should learn how to protect the game better.
Although I will say that they should keep a better eye out for drunks. I've sat next to some absolutely blasted people before, and seen them toss black and purple chips away like candy, and then stumble away from the table and probably out the exit doors and into the parking lot.
