Yeah, you might be right. But I'd be less inclined to use a CC if I wasn't getting cash back, so they'd face more competition from debit cards, cash, etc. And,

  I think essentially everyone would keep using their credit cards just as much, because debit cards are significantly riskier (to the consumer) from a fraud standpoint, and cash is significantly less convenient. Merchants can already stop accepting credit cards due to the fees. Why don't they? Because it would make their customers mad. Few businesses have customers who are more loyal to them than they are to their own (even minor) convenience. I do have a local restaurant I go to that doesn't accept credit cards and is packed nonetheless, but it's a rare feat. The points have a little bit to do with this, but not nearly as much as the convenience. What would change is that credit card companies would have more trouble luring people to switch away from their existing card to a new one. But they'd have a huge amount of extra money to spend on advertising to make up for that.
