No, consciousness is only a mystery because it has no definition., yet.
Bravo for the rest of this article. You pinned it: the hard problem is hard only because of the mind. Like for consciousness it lacks of definition. It is only a cultural, religious and functional concept.
For sure, Chalmers philosophize on nothing (consciousness, mind, etc.). They are just words coming from the beginning of civilization, when humans had little knowledge about the world and had to invent narratives to try to explain life.
