There are pros and cons to cash and cashless. For most people in a normally functioning modern society cashless is in theory convenient "better": automatic electronic transaction record (for your own use), no making change, quicker, less physical items to carry, etc. The #1 advantage for modern cash users is privacy. Some people don't want to have all of their transactions tracked and mined by others. Not considering privacy, there isn't much cash has over cashless aside from working offline, but again, normally functioning modern society.
