Why wouldn't space based solar power work for the moon, when the concept is discussed for earth?

Only thing i can think of are decaying orbits because of irregular mass distribution.

But when thinking of such concepts, why not plan for some station keeping expendables? It's not like were talking about some feeble pebbles thrown into orbit there like we have done up until now...
