If the Moon orbit was low enough to melt Earth interior due to tidal
forces, it wouldn't have taken long to bring it crashing on top of our
heads.
On an unrelated vein, we seem to be pretty lucky the geodynamo has been
going strong for so long, as this seems to limit the volatile loss to 2-5
kg/s, depending on solar activity.
Mars seem to have lost the bulk of its volatiles because its dynamo went
out.
