Yes, agreed. But my crazy idea is to start using the space junk in orbit to build new stuff in orbit, not bring it back down. The value of space junk is it's already in orbit i.e. energy already expended to get it up there. At some later time, it probably can easily be refined into raw materials like steel, titanium, or fixed like broken solar panels. Easier than converting Moon rock into new stuff. But the technology isn't here yet to do so.It would probably cost many times more to effectively collect anything in an already existing orbit and bring it back down.
