Even if the satellites are cheap -- hell, let's even say they're free -- launching things into space is not, by any means.

As for the satellites being owned by someone, how do you assert ownership on something that exists where there are absolutely no laws?

Asserting ownership is as simple as convincing a judge.

As far as I know NASA/US Government claims ownership of US satilites, so the precedent has already been set.

The launch will be cheap as soon as we build that damn space elevator (which I believe is currently technologically feasible, correct?).

What!? Try to play the other side, at least.

Whack-a-launcher is way easier than whack-a-satellite.
