We're all pretty blase about rocks; I know I am mostly. But there are
different kinds.

If it was a nickel-iron, that could be mineable nickel-iron might be a 
building
material.

If it's a chondraceous then it could have volatiles at the center- 
that's rocket
fuel right there, and there are few things more important than rocket 
fuel in
space.

Also, 'just a rock' is one way to boost spacecraft/stations- you attach 
a tether to
one end, lower the rock down, and then let it go.

Also rocks make great radiation shields. I presume everyone knows about the
flashes the astronauts can see with their eyes shut? A few meters of rock
would stop that, and increase the mass of the ISS  (less frequent reboosts).
Enough rock, and no more reboosts ever going to be needed for the life
of the station.

Isn't use of 'rocks' like this why we are trying to go into space?
