That is my point. I can be near a rock and an ant can be closer to the rock. The observer dependent position of the ant does not affect my proximity to the rock. We would have to agree on a frame of reference before we could begin debating my absolute position relative to said rock.
Your post and the previous are making the materialist argument (which in real life I agree with.) I was trying to further explain the Christian argument for free will in a world where omniscience is possible. An omniscient observer doesn't affect the lived experience of free will for anything else. The watchmaker god theory is a popular way to reconcile this point. Even if free will as a discrete and measurable phenomenon does not exist e.g. one cannot show me they have x units of free will or whenever, that does not change the experience of free will for the individual.
Arguing for or against some imagined omniscience by switching the frame of reference to that of an imagined all knowing system or all encompassing formula and then using that framing to invalidate choice isn't very sound reasoning. It may or may not be correct and it is falsifiable but we can't test it in any meaningful way.
