Also, if the loss of an asteroid worth of computronium is a problem,
you could always set out with the aim to relativistically hurl back a
lot more matter to replace the asteroid with; that way, you can
balance the cost of the present matter with the gain of a lot more
future matter (heavily discounted of course because of elapsed time)
and have the whole enterprise be worth the trouble for the net gain in
computronium alone.
