Okay, now I feel like I understand your main point better.
I think I have just another point of view on the example. My point is that the example itself seems a bit artificial.
The human brain still is not conquered by reductionist modeling. So we don’t know yet if there is a possibility to reduce consciousness (we are talking about the feeling of joy, that means about brain and consciousness) to some systems and parts without losing crucial properties of consciousness. At any level.
Bearing that in mind, the example seems a bit meaningless in both cases:
The case where you reduced consciousness by modeling on an adequate level
The case where you reduced consciousness by modeling too low-level
I think it’s too theoretical to say what you actually did wrong if you don’t know how to do the same thing right (that is if you tried to apply reductionism in the very same conversation but in the right way).
With that said, it looks to me like you could just omit the example from life and all the context as poor evidence, leaving the statement about low-level modeling alone.
