There is a mistake on the diagram. The rightmost ellipse should say "you don't need a blockchain". The rest is accurate.

  I'd say "you could use a blockchain". It does have some uses.

  I agree. There's no need for a blockchain if two parties can find a mutually trusted third party: use 2-of-3 multi-signature with one of the public keys being that of the trusted party.
