""They" is about the dumbest son of a bitch I have ever met."

And yes, I agree, 'they' often are wrong. The wallet is not just for carrying cash in, it carries your identity which many people are not about to hand over to a centralized database of iris scans, and all a credit card along with your signature or pin number is is an identity. Wallets also carry other more personal things safely - like the picture of your wife/girlfriend/child etc, your receipts and even somewhere to put your ultra high capacity super micro usb pen drive.
