The point is that "what we call the Moon" IS the Moon.
The question is: *what* is the moon, in the fundamental TOE (that we
derive from comp, for example).
If not, you become instrumentalist, and just abandon the idea of
searching a fundamental theory.
I am not sure of your motivation here. It looks like "don't ask what
is the fundamental nature of the things we talk about"?
My point is that such nature will depend of the fundamental principle
we agree on (if only for the sake of research: agreeing on axioms does
not mean knowing they are true of course (pace Craig).
I am just saying that if comp is true, existence of physical object
must be explain by "machine's theology or self-referential logics".
Wheeler was not so far from this.
