1st: Nice Try. In god's words: I'm being, she is nothingness. Suddenly there is the cosmic being.

2nd: You are contradicting yourself with "demons are corrupted souls which means they are not souls anymore", but I give you a pass since Purgatory happens to be populated with monster souls. Maybe same shit. But even then, why would demons share weaknessess with ghosts? Salts, burning the body? That imply that they are the same species-wise.

3rd: The castiel that was ressurected by God after freeing leviathan wasn't quite right, isn't he? He forgot things. Why would god do it? To fuck with Dean and Sam? To punish him? But that would require the same castiel to be punish, not a version of him. Needless to say, maybe you are right, but at this point it is speculation. God saying rebuilt might also be a technical term of his part describing gathering of Castiel's scattered Grace, so we don't know for sure.

Overall, the retcon is strong in this one. Especially the first.
