Fact 1: the person went to the store because of the behavior of chemicals etc. Fact 2: the person went to the store to buy milk.
These are not “merely” two different models: they are two different facts about the world.
Not independent facts, surely. The person went to the store to buy milk because of the behavior of chemicals, right? Even longer chains … because they were thirsty and they like milk because it reminds them of childhood because their parents thought it was important for bone growth because … because … ends eventually with because of the quantum configuration of the universe at some point. and you can correctly shortcut to there at any point in between.
I said they were two different facts, not two independent facts. So dependent or not (and this question itself is also more confused and complicated than you realize), if you do not mention them both, you are not mentioning everything that is there.

Hmm. I don’t think “mention everything that is there” is on my list of goals for such discussions. I was thinking more along the lines of “mention the minimum necessary”. I’m still unclear whether you agree that physics is sufficient to describe all events in the universe including human behavior, even while acknowledging that there are higher-level models which are way easier to understand.

It is sufficient to describe them in the way that it does describe them, which certainly includes (among other things) all physical motions. But it is obvious that physics does not make statements like “the person went to the store to buy milk,” even though that is a true fact about the world, and in that way it does not describe everything.
Ok, one more attempt. Which part of “the person went to the store to buy milk” is not described by the quantum configuration of the local space? The person certainly is. Movement toward and in the store certainly is. The neural impulses that correspond to desire for milk very probably are.

All of it.
The person certainly is.
The person certainly is not; this is why you have arguments about whether a fetus is a person. There would be no such arguments if the question were settled by physics.
Movement toward and in the store certainly is.
Movement is, but stores are not; physics has nothing to say about stores.
The neural impulses that correspond to desire for milk very probably are.
Indeed, physics contains neural impulses that correspond to the desire for milk, but it does not contain desire, nor does it contain milk.
