Capitalism is *all about*, at its core, building decentralized systems which on inspection turn out to be centrally controlled, or controlled via a "one dollar one vote" democracy of the five or six richest people in the system (in other words informal centralization, without the committee that makes the decisions having a name).
The decentralized internet systems that capitalism builds reflect this. There's lots of examples of it. Bitcoin, Ethereum, Bluesky.
