The "end game" for a lot of merchants is not to get robbed. I don't think that's an unreasonable concern.
My endgame is not to get robbed, as had to shut down another cc today after it getting hacked. Admittedly it is only the third time in about 10 yrs. Never had anyone steal cash from me. Certainly it is reasonable for the merchants if it helps them, especially if their customers are willing.
For the people willing to keep all their finances electronically, good luck to em. With absolutely no proof, got a feeling much more money is stolen electronically than cash stolen.
