Space manufacturing is a real thing, there are already companies trialling it. The factory is small, satellite sized, and it deorbits when the manufacturing run is done. The results are protected enough for them to be picked up from Earth.
The justification (today) is that you can do very exotic things in zero-G that aren't possible on Earth. Growing ultra-pure crystals and fibre optics and similar.
