I believe the "Wat." is directed at the mandated-by-laws-of-physics fact that it adds a 2.6 second lag, and that at constant path loss and frequency it requires antennas have 768 times larger diameter (or close enough, the maths works out that it's the distance to moon divided by distance to wherever in LEO your default case is and all the other things involved cancel out).

This factor (and that it applies to all EM including both radio and optical) is also why we had to wait for lunar orbiter missions to get photos of the Apollo landing sites rather than take a picture with Hubble.

Oh, and then there's the problem with the moon having much longer and much darker nights than anywhere on Earth that isn't the [ant]arctic circle, though I have previously opined that anyone who isn't ready to put a few thousand tons of aluminium onto the moon and make a circumpolar power line *simply isn't ready for any plan like this in the first place*.

And the fact that there's only one moon, so half the planet doesn't get any signal from it at any given time.
