It's especially endearing to me because it's my primary objection to anarchists (of whom I have several as friends)- that the system they envision just isn't stable, and we arrived at the system we have now for that reason.
Also, as Yvain pointed out in his excellent article[0], we might be fucking ourselves over big time with this drive towards decentralization and trustless systems. As we fight against corruption and abuse, we're building systems that don't allow us to coordinate even in principle. Today it's tax avoidance and buying pot on-line, tomorrow it will be untraceable trade of fissionable material and weaponized biotech.
Building trustless systems seems like a cool hack, but I think we'd be better off working on a way to improve coordination.

Many socialist and anarchist ideologists are/were perfectly fine with centralisation of production, as long as decision making is decentralised, and participation is a result of free choice and can be withdrawn.
The capability of decentralisation in Bitcoin is important because it acts as a safeguard against forced centralisation and coercion. As long as the capability remains, whether or not people for practical/efficiency reasons opts for centralisation ought not cause most anarchists any major concern.
I'm probably misunderstanding something, but isn't it more that blockchain technology allows decentralisation, while dominance of any particular deployment supports centralisation? As I understand it, once Bitcoin is centralised, the 51% can control it as they wish, and the only alternative is to set up a wholly separate Bitcoin2 chain, or another altcoin.
(Again resulting in cryptocurrency being a bad store of value.)
