If any other kind of agent can make market moves, then that agent has to supplant humans at the 'top'. For example, the pet market is absurdly large. What drives this market? The actual needs of animals? Of course not. It's the wishes of humans that make that market as big as it is. It doesn't even have to be that humans are smart enough to control the new market-playing agents. It can also be that human desire can so vastly dwarf whatever external agency has a wish to be in the market that the whole industry ends up catering the wishes of the humans. Right now, human desire drives the market for robots. Can you even imagine a point at which robots could develop enough agency to even come close to supplanting the human desire for more and better robots? When does the tail stop wagging the dog here? People sometimes forget the sheer scale of human economies. Sure, maybe your pet non-human agent might be able to command a few hundred thousand in market activity. Is it even going to be notable over all the other existing types of non-human agency already on the market, like pets and HFT?
