Cheaper mass to orbit is undoubtably good, but not all mass, shielding or otherwise, needs to be lifted from Earth.

Yeah, even unprocessed Lunar or Martian regolith will help, provided the added mass does not cause issues - fine for space stations, more difficult for ships that have to drive the shielding around.
