It does, or else how is the moon's rotation locked to the earth ?


So the entire product of earths gravity is given the attention of the
satellite.

A point I agree with. As is the obverse. The entire attraction of the
earth for the moon is occupied in centralising it in the position it
maintains in the two body problem. So how come there is enough left
over for playng around with its puddles?

Physics in the reply might not come amiss.
