Why is it cheaper to ship all of the materials to space, then to the moon for assembly (which also includes shipping all of the people and supplies to keep them alive), then back into space vs just…

building them on earth and then shipping them up?

We’re not exactly at a loss for land over here.

In situ manufacturing. You just have to send enough to build the thing that builds the factory.

It's not like satellites need anything like computer chips, which are finicky things to build that require parts with a sole supplier on the entire planet.

You can make propellant on the Moon (aluminum based solid fuels), and the energy to get into orbit or into deep space is far, far less that from Earth’s surface.

What do you mean, "people" ? I'm pretty sure Musk is only expecting to send self-assembling Optimus robots [1] to do the whole manufacturing.

(Oh, those times where you try to be sarcastic and realize: "wait, maybe that's the actual plan".)
