What I mean is: if we're sending undesirable things like garbage into space, why do we want it on the Moon? Why not just launch it out of the solar system, or into the Sun? There doesn't seem to be a good reason to favor putting it on the Moon.
> Energetically, it costs less to shoot your payload out of the Solar System (from a positive gravity assist with planets like Jupiter) than it does to shoot your payload into the Sun.
This is kind of my point regarding the Moon. It's harder to hit the Moon than to miss it, so why aim for it?
