Yes, I don't think I phrased it well, but I didn't intend to assume that there is a single Robot Mega Corp.

> The more humans we replace by robots, the lower the cost of goods will be

Most physical goods have two parts: materials and labor. Even if robots were to bring the labor cost to approximately zero, we still have the material cost. So you're right that you don't necessarily have to own the robots to successful, but you do have to own resources.

Even "resources" primarily only cost money because of the labor it takes to discover them and then remove them from the ground and refine them. In theory there are some things that are genuinely scarce (e.g. energy or specific elements) but so what? Most of them have substitutes, and the fewer labor costs have to be paid the more substitutes become viable. Have the robots mass produce wind turbines or solar panels out of low-scarcity materials, or mine space, etc.

Even in the most pessimistic case where you have a valuable scarce resource with no substitutes then you have something to tax which will produce revenue that can be used to supply necessities to the public.
