>By the way, you can transfer cash without any intermediaries. You literally just hand it over.

Why would you want that? What happens if you have a fraudulent transaction? How is it reversed? What about coercion? Blackmail, etc.

Yeah, that's why you use escrow, or an intermediary service. By the way, I never claimed you should use cash. In fact, most of the criticism I have towards Bitcoin also applies to cash, as you've sarcastically pointed out.

This is one of the growing pains of bitcoin that will have to be worked out. You can send bitcoin to addresses that nobody holds the private keys to and those coins will be gone forever. There are likely already several hundred thousand or millions of bitcoin lost this way.

There is no reversal of a transaction, the ledger is immutable.

With all of that said, bitcoin was not created to solve crime.
