To be fair, they haven't been free-riding. Credit cards force prices up by about 3% for a reason, and checking accounts don't give you market yields for a reason.

But yes, for me personally, I much prefer deterministically losing 3% to risking 100% (and incentivizing physical attacks).

Fair point. The only places where you can pay a lower price when using cash is at small convenience stores.
