When you take Bitcoin out of the blockchain, what you get is a decentralized (or centralized but distributed in this case) relational cluster database. The purpose of a blockchain is to allow you to interact with other nodes without requiring trust. For any other purpose that doesn't have this requirement, there are actually much more efficient alternatives.
Exactly.
It's weird watching everybody hopping on "blockchain technology" without even having a proper use case for it. It seems to me, that "blockchain" is the latest buzz word used by managers who don't have even the slightest expertise in its technological implications. But they want to feel smart and demand "blockchain technology" for any database...

What flabbergasts me as well are the various attempts of conceptually separating Bitcoin from "blockchain technology", while in fact the security of the blockchain totally depends on the financial incentive (= the value) of Bitcoin.
ya.ya.yo!
