Thank God for small favors; I'd like to see what the energy required to
get get something from the Kuiper belt down into Earth orbit would be like.


Nor are trips to the asteroid belt. I suspect both metallic asteroids
and asteroids with ice interiors exist among the NEOs.


Metals probably, at least for some.
Ice? Depends how close to the Sun they get, because your concept
basically describes a short period comet, with the volatile boil-off
that implies.
