Remember, just to develop the industrial base on the Moon to make this

And more importantly, have a way to return to earth the ore that you have
mined on the Moon, and all of this should be cheaper than the ore that is
mined on earth.

I'm not sure that is the point. My question is: is it cheaper to mine and
process materials on the moon, and use them there in finished products, than
it is to fly finished products there? Or, are there materials on the moon
that cannot be gotten on earth?
