Cash is convenient in some ways, not so much in others. It's convenient for making small purchases and keeping the transaction anonymous. On the other hand, it's inconvenient when you want to be able to prove a transaction [my bank paid a deposit into your bank] and also inconvenient for large transactions.

On the other hand, "convenience" is a contrived reason to favor cashless transactions. As if the whole purpose in life is to reduce friction from our lives. It's not. Oh, it frees your time up to do other things. As if people didn't have enough time. The main thing lacking for most people when it comes to time is time management and allocation. That is, people who might save an hour's time by automating activities don't go out and spend that hour productively. Likely they'll find something else that'll use up their time.

So, we have people who work in industries which are automating jobs away [say Uber, or even supermarket automation, HFT, etc.] but who on the other hand want authentic hand made or bespoke items. Why not go for the mass produced item from Walmart they helped get produced and are more "convenient"?
