I think this take on decentralization and structurelessness sort of misses the point. Of course it's true that all systems that do anything useful have structure somewhere. The point of various movements for "decentralization" are where to locate that structure. Jo Freeman's essay correctly points out that "structurelessness" in activist movements locates that structure in social influencers and insiders, which is probably not desirable for most action-oriented purposes.
Which layers or pieces of the system we choose to anonymize and make fungible are an important architectural choice, and DeFi/crypto simply expand the scope of available choices in that regard. Prior to their existence, it was not possible to locate structurelessness in the layer that crypto does. Whether locating it there proves to be useful remains to be seen, but it is clearly an expansion of our capabilities, in the same way that Paxos and Raft are for databases. Yes, they still have structure, no, that does not make them useless.
