Unnecessary though productivity outpacing demand as far as I've understood it. In Marxism what they call "full communism" is envisioned to be the "final state of humanity" where productivity is described to be higher than the sum of needs and wants - everybody can help themselves to anything from the warehouses. Obviously very utopian, and I'm not sure there ever was any detailed analysis on how a society a would actually function in "full communism" - but I don't think the economics of The Culture would be that far off if you would describe it to someone of those views. Early Marxists were much a bit more practical, more focused on critiquing the practices of their contemporary societies than envisioning the details of their utopia.
