No, I would say that all of those four words would be an accurate description. It uses cryptography, it's digital (you agree with that part), it uses electricity and communicates information over a network and it is virtual.
If you would prefer the title of the whitepaper to be "Bitcoin: A Peer-to-Peer Digital Electronic Cash System", you might as well call it "Bitcoin: A Peer-to-Peer Crypto Digital Virtual Electronic Cash System". Which wouldn't exactly roll off the tongue.
You could put any number of details in the title, but I certainly wouldn't say that he made a mistake.
Haha true that.
