@cjd Needs a qualifier. I distinguish "centralized capitalism" vs "decentralized capitalism" (and in-between).
It is similar to the distinction between centralized "social media" like Farcebook and decentralized like SSB and in-between (federated) like Activity Pub or Matrix. or email.
It is like centralized internet vs OG internet where you connect to peers that you meet personally. "Hey, you want to make a peer connection?" (typically a 115kbps rs232 back in the day)
Cjdns is trying to make decentralized internet practical again for Normies - runs on a modern ethernet physical layer or a virtual tunnel. (And yes, yggdrasil as well.)
The Bible describes the ideal economy as "every man under his own vine and his own fig tree". I.e. the actual worker actually owns the means of production. Not the communist govt. Not the multi-national corporation. The individual worker (and no, stock certificates don't count).
New tech starts out centralized - steam looms, computing, plastic parts, space travel. As the tech advances (absent power hungry market distortion) it decentralizes - a powered loom in your workshop, a super-computer in your pocket, a 3D printer in your den, a family spaceship in your back acre (oh wait, Elon isn't quite there yet).
The issue with centralized capitalism and centralized social media is getting Normies to understand what we are talking about. I use the "know your farmer" analogy. Centralized agriculture is also a huge problem The answer is either "grow your own", or if like me you can barely turn out a few squash and berries, "know your farmer". You meet and talk to them, look at and admire their farm, noting that the cows actually eat grass and the chickens actually eat bugs. And you become a loyal customer.
