I'm not sure how many jurisdictions force them to allow cashing out. If I recall correctly California law says they have to, but only for relatively low value ($10 or $5 ?) so not sure how effective that is. So I doubt the CC companies are too concerned. Of course if you are selling them below face value and it wasn't your card, its a different calculus.
