>>sending raw materials up there

That's what asteroid mining is for.

>>service technicians are necessary ALL THE TIME

Optimus is already very well tele-operated. Even though over time it can likely be trained to do specific tasks far better than even humans.

It’s not necessarily cheaper energetically to get stuff from an asteroid than from Earth. You’d have to accelerate stuff from a wildly different orbit, and then steer it and slow it down. Metric tonnes of stuff. It’s not physically impossible, but it is wildly expensive (in pure energy terms, not even talking about money) and completely impractical with current technology. We just don’t have engines capable of doing this outside the atmosphere.

Delta V from just about anywhere in the solar system is lower than launching from the surface of Earth. You could launch stuff from Mars and bring it back to Earth orbit with less energy than launching it from Earth. The rocket equation is really punishing.

Right. The alternative is not to send materials from Earth for processing in space, that would be stupid. We send finished stuff, which were manufactured on the ground. But you don’t mine finished widgets from asteroids. You mine ore that needs refining and processing before being used to manufacture things. This ore is orders of magnitude heavier than the finished products, never mind all that’s required to do anything useful with it.

It can't even serve popcorn in a diner.

I think you might have no sense of what it takes to go from a raw mined material to something that can be used in a factory. I am not saying it cannot be done. I am just saying it cannot be done in a way that is cheaper than on earth.
