Things like platinum notwithstanding, It will almost always be more expensive to go get things in space than on earth.
Hell, even on earth it is often too expensive to get metals like iron if there isn’t rail or a port nearby. Imagine having to fly iron ingots around and the associated aviation fuel cost. Whatever crazy fuel bill you’re imagining, multiply by a hundred or more if you’re imagining getting it from space.
No, all of those metals in space are best used to build some future version of our civilization _in situ. _
