What motivation does the manufacturer have to make those parts available to you?

It'll probably come down to a combination of regulation from an entity like the EU and the economic reality that it's easier to make a robot that has OEM parts that a consumer can access out of your supply chain.

		You've retreated from "buy one humanoid robot and it can make as many more as you want from scratch, it's like asking a genie for free wishes" to "there could be a regulatory framework that would require the manufacturers of humanoid robots to make a retail parts pipeline that allows your humanoid robot to build another humanoid robot at a cost lower than what the manufacturer would sell one for." You didn't talk about the cost, but what's the point of having your robot assemble parts that the manufacturer will sell to you, assembled, at a lower price? It only makes sense if it's cheaper.
