We're in agreement. Since USD is a physical store of value, it suffers from problems like robbery. Hence the need for banks.
With bitcoin, you don't need a bank. I have a 24-word passphrase in my head that can be converted to my private key—a "brainwallet". I know it, and my parents do. It's not written down or stored anywhere. It simply isn't physical.
With those 24 words, you can unlock all of the value I have stored in bitcoin.
It's utterly amazing.
