The trick is bypassing the human consumer as well. Companies satisfy (human) consumer needs as a byproduct of profit maximization. But human consumers are inefficient. They have to sleep, require medical care, etc.

A purely machine economy would be far more efficient. Therefore in the limit we should eliminate reliance on human labor and consumption to build a more perfect and efficient world.

Idea! Maybe these now redundant humans can be turned into a kind of battery, so they serve as a source of energy for the machines?

Perhaps it's then smart to make the humans have a brain/computer interface, to make then dream/think they are living in a normal society so they don't revolt.

You jest, but isn't this the logical conclusion? A sufficiently smart AGI has no need for humanity, at all.

The humans consume to fulfill needs, how do those needs get fulfilled in a post human economy?

The "economy on a chip" thought experiment .
