Instead of profane name-calling, you'd do better to explain how "the size of the economy can never exceed X" is not a good paraphrase of "The economy has been based on endless expansion. That is not sustainable."
And to explain why obtaining thousands of tons of raw materials from asteroids, and then transporting them hundreds of millions of kilometers, partway down into earth's gravity well, is superior to obtaining raw materials from the moon, and then transporting them just a few kilometers to another location on the lunar surface.
We're still decades off from being able to bring back any resources.
You must not comprehend the concept of space-based solar power, because microwave power transmission was proven to work decades ago. The beam of massless photons would travel from the moon to the earth at the speed of light, then be converted to electric power by a high-efficiency rectenna. Manufacturing PV cells on the surface of the moon would be the biggest challenge, but "bringing back the resources," i.e., the energy collected by the system, would be trivial.
We want to put a radio telescope on the moon.
You don't come right out and say it, but you imply, that a radio telescope and a lunar-solar-power system are mutually exclusive goals. So let me disabuse all readers of that notion. A radio telescope must be situated on the far side of the moon in order to shield it from earthly RF signals; and a solar power system must be located on the near side of the moon so the microwaves can be transmitted to Earth; so the two projects would in no way compete with each other for lunar real estate. The knowledge base built up during the construction of one would be highly useful to the construction of the other.
And are you proposing that human workers, not the robots that you so disdain, mine the asteroids and build the radio telescope on the moon? If so, those projects will never be feasible, and Neal Stephenson would be disappointed in you... he didn't pour his heart and soul into Blue Origin, for advanced space vehicles to have no grand missions to perform.
