Pick the sun as reference: the moon rotates. Pick the earth as reference: the moon rotates. Stand on the moon and pick any star as reference: the moon rotates.
From which reference frame would it not rotate?

Yes but from the point of view of the earth the moon does not appear to be rotating around its own axis since it is tidally locked. In that sense it’s confusing to me to distinguish it from everything else on earth but the comment above about centripetal force clarifies this for me I think
We can see the stars moving behind the moon, thus it must be rotating with us.
