It hasn't been since at least 2018; authorities regularly seize millions worth of bitcoins together with drug dealers, and have been openly bragging about their de-anonymization successes as early as 2019.
> what's the authoritative history lies with Linus Torvalds.
I agree with your point about distributed consensus in general, but there isn't really a single authoritative history of linux, there are tons of important forks simultaneously maintained.
As for deanonymization, that doesn't seem to be very common. Compare to the rate at which people get busted by street cops for buying drugs.
What does that have to do with blockchain? Is bittorrent to you "blockchain for downloads" just because it's decentralized and has hashes?

They use similar data structures, but blockchain is more than a Merkel tree, it also includes a consensus algorithm.
The "Bitcoin" application is a tool useful for buying and selling recreational drugs without exposure to the physical risk posed by cash transactions. Edit: That is, the physical/financial risk posed to you by the other party or third-party robbers. Legal risk is probably also reduced: law-enforcement deanonymization attacks seem much less frequent than busting people with drugs on the street.
Blockchain-based markets in general enable transactions without revealing personally identifying information to the counterparty or platform while circumventing regulatory restrictions on conventional transactions.
