I fully disagree. If you were to declare by decree that all companies must be worker owned, you would create a vastly different economic and social structure from if it was actually owned communally, for example, you would have serious differences in income and capital ownership due to market competition, as well as incentives against vertical integration. This is not extensive government intervention, it boils down to a simple change in property ownership laws. Also, loans are fully compatible with worker-owned companies, so you can still have capital transfer. So I disagree very strongly that this "boils down to irrelevance".
