A gaping hole in your argument however is with regards to the nature of emergence.
You’re thinking Linear Causation.
If consciousness emerges from the interaction of the complexity of its parts, this does NOT MEAN the emerging consciousness is BLOCKED from influencing the very system that is CREATING IT.
I may be missing something basic here, but as well written as it is, I do not believe your argument is sound.
Consciousness is not a chicken [or] egg situation.
Follow this scenario:
Complex physical system creates beginnings of consciousness.
Beginnings of consciousness back-influences complex physical processes.
Complex physical system receives feedforward which further refines consciousnes, which then influences complex physical system.again.
