Visa and Mastercard aren't currencies, they are payment systems. Furthermore, max TPS and day to day average utilized TPS are very different, that is a weird comparison. The confusion is that USD can change "hands" in so many different ways, it does not have a set transaction latency or bandwidth, if we did a best case analysis the latency would be me handing a tenner to the guy at the grocery store, with the bandwidth of 3.5B people handing a tenner to the other 3.5, that is a lot better than 50K TPS. Obviously not a serious suggestion, just trying to explain why the question of speed needs to be nuanced.
