Space is only ~60 miles away, that's not that much wire. Getting one end up there is left as an exercise for the electrician....

I think it all ties together. Ground potential as in sticking things in the actual ground is in practice pretty much the same as that theoretical potential at infinity, because space has enough charged particles flying around to equalize the imbalance. But it doesn't really matter from a practical perspective when making circuits.
