I couldn't agree more! Government run digital currency just can't work. Slow and cumbersome governments not only can't keep up with tech, they would use the currency as a way to spy on citizens. They could also dictate what you are allowed to buy and where you can shop. Talk about a nightmare!
The greenback will remain king of physical currency for the time being. That is until crypto becomes accepted as payment in most retailers. It's just a matter of time...
The US dollar isnt a physical currency anymore. Very few transactions are done using banknotes. What people overlook is that all currencies are basically digital.
Crypto payments are still going to be denominated in USD. It is not going anywhere.
