That’s kind of the point of horseshoe economics, “the people own the economy” is impossible to implement without an intermediate agency to actually oversee the day to day of said economy.
What’s that entity? The government. Any conceptual type of non-state entity would just be governance in nature regardless of title, and therefore still essentially operate as “a state” if not the same state that the federal government exists as.
Though as someone who works in modern IT I foresee the future of robotics and AGI allowing for the kind of economic automation that would make communism inevitable eventually as jobs are reduced over time in the course of the next hundred or two hundred years.
