There are many many more issues in a cashless society. Imagine a power outage (sadly, we're getting close to regular ones here in europe)... how will you pay for anything if POS terminals don't work? Imagine protests like the ones in china now.. (and not that long ago in canada)... protesting.. hungry? Wanna buy a hotdog or noodles? No cash? Use some digital card/app.. there's a paper trail you were there and your account is locked. Banks wanting to earn a bit more money? Some people spending more money at liquor stores than at fitness stores... that information would be valuable to insurance companies. Want to buy an XXXL buttplug? Now there's a paper trail from a XXXL buttplug store... government changes (your leader doesn't want to use dolars anymore to sell oil, someone organizes a coup,...), and you're being thrown from a rooftop. etc.
