Caledonian—the addition of p-consciousness has no physical consequences. To infer that it has “absolutely no consequences of any kind” is obviously question-begging against those of us who hold that there are non-physical facts (e.g. what it is like, subjectively, to be in such-and-such a physical state). The zombie world is appreciably different from ours in these other respects.
Incidentally, the principle you depend upon is self-defeating. Consider:
(Scientism): A claim is coherent only if it has scientific implications.
What are the scientific implications of this principle? What empirical test would show whether Scientism is true or false? It is incoherent by its own lights.
