... It's slower/higher, actually. This sort of tidal interaction
has resulted in the tidal spin-orbit locking of most of the large
planetary satellites in the solar system. It is also responsible
for the volcanism on Io and the librating orbital resonance lock
of the inner three Jovian satellites. ...

1) Is it correct to think that for ideal rigid (spherical or ellipsoidal)
Earth and Moon, synchrinization would be an infinitely long process?
It could only occur by coincidence.

2) Is it correct to think that for ideally elastic (deforming slightly
without internal friction) Earth and Moon, synchrinization would be
an infinitely long process? It could only occur by coincidence.
