Regarding your first point, it was never the claim that such control is unique of capitalism, rather that it is qualitatively different in capitalism. Other have taken the point about the relationship to capitalism in the other direction:
>Once value is deemed to reside in individuals, everything changes. Firms no longer “create” value; they can only strive to realize the value that already exists in individual space. In this way, distributed capitalism further expands the concept of ownership. Not only is share ownership dispersed, but value itself is dispersed. Individuals “own” the sources of value, as all value originates in their needs, and all cash flows from the fulfillment of those needs. . . . As the origins of value and the source of all cash flow, individuals can no longer be written off as anonymous “consumers” who sit at the far end of the value chain, devouring the value created by managers and underwritten by shareholders. Instead, they are preeminent stakeholders in the new collaborative structures that are fundamentally aligned with the requirements of relationship value realization.
