To maybe get a little carried away with the sci-fi for a minute, why does the Actuator need to cost anything?

When the tree of costs that make up a product are traced, surely all the leaf nodes are human labour? As in, to make the actuator, I had to pay someone to assemble it and I had to buy the parts. Each part had a materials cost and a labour cost. So it goes for the factory that made the fasteners, the foundry that made the steel, the mine that extracted the ore.

Shudder to think of how to regulate resource extraction in a future where AI humanoid robots are strip mining and logging for free.
