I find this to be less of a whitepaper and more of an opinion piece. For e.g.

"For example, two business parties transacting would not need to maintain their own record of the transaction and would use the blockchain as a single source of truth instead."

Ummmmmm...isn't the whole idea of blockchain that we all have a copy (our version of the truth) and a transaction is validated by several participants or miners? That's basically how we get rid of the middlemen? The sentence is clearly trying to convey that this is somehow more efficient than a current system based on a centralized authority, but there's no actual evidence that this is true.

Blockchain might bring efficiency to an industry like shipping that currently uses a VERY inefficient system, but it's disingenuous to tell others (especially if you are trying to sell something), that it is more efficient than a well implemented centralized system.
