Just because your current theory of apples refers to quantum fields doesn’t mean quantum fields are essential to appleness. I would think your concept of apple is continous with the concept of apples before the discovery of quantum fields. And even if we abandoned belief in quantum fields we would probably still keep the concept of apple and it would survive such an ontological shift. Anything that has a true definition that would involve quantum fields could not survive such an ontological crisis.

Thanks for pointing out this argument, I might add a variation to the list.
