There is a mechanism in the brain that has access to / represents the physical damage. There is no mechanism in the brain that has access to / represents the aversive response to the physical damage since there is no meta-representation in first-order systems. Thus not a single part of the nervous system at all represents aversiveness, it can be found nowhere in the system.
First, you can still infer meta-representation from your behavior. Second, why does it matter that you represent aversiveness, what’s the difference? Representation of aversiveness and representation of damage are both just some states of neurons that model some other neurons (representation of damage still implies possibility of modeling neurons, not only external state, because your neurons are connected to other neurons).
