I want my digital cash to work like regular cash. I need to pay the lawn guy, send an iMessage. I wanna buy lunch, swipe my phone and pay with the money in my phone. I don't need the charge going through my bank or some intermediary.
I want freedom to use my digital money the way I want without someone holding my account hostage, if I do something wrong. Additionally, I have no problem losing my money, if I send the money to the wrong person or lose my phone.
That's good usability-wise, but it still has the problem of central banks being able to create money (diluting your wealth for their benefit) and also being able to cancel you, or someone you want to pay, out of the system. It's a horribly powerful way to control people.
