They do not hold concepts, they are simply physical items behaving in accord with physical principles. You as a human interpret them (wrongly) to hold concepts. You can as well interpret them to be something else. None of your interpretations change the physics and the physics have no mention of abstract concepts and can be interpreted to be any number of things. None of the interpretations make that particular interpretation a concrete implementation of it.
