By that logic market makers in the stock market are basically like a casino too. No one is of course guaranteed to win in anything but at least the stock market doesn't ban you for making too much money like a casino does.

The casinos won't ban you if you take too much from other players. They ban you because you take to much from the casino itself.

If you somehow caused some exchange to consistently lose money, I'm sure they'd cut you off.

I mean, yeah, pretty much.
