I just meant that if I value, say, the security afforded by land that's been cleared of humans, and between them my owned AIs can deliver this as a 'surplus' outcome, just by processing resources available at low or no cost (sunlight, atmospheric gases, processed carcasses, etc.) then letting them run amuck is still 'economically valuable' to me, but doesn't require any human input, or a human counterparty. Very reductive example, but you can imagine a much more complex economy where a multitude of similar arrangements interact/compete to deliver outcomes of this type.
