Since you're injecting this into the thread, I'd say it's more privacy and choice. I like carrying cash in my pocket. It's usually a fraction of what the phone in my other pocket is worth. If you've had a lost or compromised credit or debit card, it's cancelled and you're out of luck until the replacement is in hand. The only exception was when I had some fraud on my Amex, once I confirmed the card was in my possession, they kept the card turned on for chip purchases only until the new card showed in two days. That was pretty refreshing compared to the kneejerk debit card vendors.
I use my Amex for many purchases, and I know that in exchange for the benefits I receive from using it, I'm leaving a trail. It's a choice I make, I'm not keen on being told.
