This is always brought up as an argument against cashless. I don’t get it. I’m quite passionate about tracking, collection, and use of personal data. But I really couldn’t care less about my day to day purchases. My bank knows that I buy a coffee every morning and lunch from a local vendor, and some groceries or dinner in the evening. My bank won’t use this for any kind of targeted advertising and I trust them to keep it secure. This data seems so unimportant compared to the frustration of cash. The second I step foot in a cash economy I start having issues with large bills (do you have a smaller note etc), losing change, having to keep on visiting ATMs. It’s extremely irritating once you’ve gotten used to cashless. What is everyone buying on a daily basis with cash that is so secret the banks and governments must not know?
