Earlier quoted context omitted.
Satoshi called it digital cash actually for a reason, not cashlessness. It has similar properties to physical cash, as the ownership can't be taken away trivially. The problem is that people are still waking up slowly. For me the Cyprus bail-in in 2013 was the wake-up call that I need full ownership of my assets.
The key issue with using Bitcoin as a digital form of cash is that Bitcoin lacks a key property of cash: fungibility. Combine this with the transparent nature of Bitcoin's blockchain and you have a currency which is an authoritarian's dream and not a currency that could/should replace cash.
I agree with your broader point, which is why I prefer monero.
