sure... but that means the three options are: "free will exists in atomic physics" "free will doesn't exist" "free will exists but cannot be studied". I find only one of these to be an acceptable answer.

One of those answers may be acceptable, but their acceptability cannot be studied.

yeah but you could make this argument about anything. For example: Bacteria can cause disease. Disease is metaphysical. Disease does not exist.

these are not generally considered to all be equally plausible!
