This would just be Solution By Fiat. Hardly a very dignified thing for Science to do.
It isn’t solution by fiat; the idea isn’t to add just that statement to science. Rather, the idea is that such a statement already seems probable from basic scientific considerations such as those discussed in the post.
EDIT:
I see now that this is not relevant. The point of the zombie argument is not to refute such considerations, but rather, to illustrate the difference between “the hard problem of consciousness” and other sorts of consciousness.
