Your analysis is exceptional. My belief is that the card would function like Venmo, a fee-less P2P payment system, but replicating the reward benefits to the user. What you're presenting is definitively the catch 22 serving the bottleneck to payment processing, but the belief is that removal of intermediaries nets consumers and companies a profit. Operating on a fixed monthly cost to merchants is then uniquely enabled because of the lack of high variable costs of existing payment methods, allowing me to have the 'cheapest product' so to speak in a commoditized industry.
