I've always felt that Dennett has side stepped the question here. The 'hard problem' here is to explain how a set of physical processes give rise to consciousness or sensory experience at all. In other words, why the lights are on.
As far as I can tell, consciousness is literally the one thing in the universe that can't be an illusion. Even if, in the extreme case, we're brains in a vat, etc.
