Humans and Robots test case

Surely, if robotic technology develops to the point where all
orbital equipment, factories, processes can be constructed without
local human oversight, then why even embark on a habitat project.
There would be no need, nor any work, for the humans and the cost
couldn't even be justified by the need to have workers in orbit. How about this: the presence of the automated/teleoperated infrastructure in space pushes down the price of space construction to the point where the constructions costs of Island One would be only about 10,000 times the price of the ritzier properties in the choicer locales here on Earth. That would result in space habitat construction being worthwhile just for the real estate sales alone. Don't necessarily expect it to go down that way, though. Just speculating on different scenarios.
