If they banish all demons from earth, would that include bound/sealed demons? So they might free her by sending her to hell, where as a KoH, she would be one of the highest ranked demons. So if crowley still lives, he will have serious competition for the throne and she would want lucifer freed. The banishing would seal the gates to hell, but could demons still be summoned, for things like crossroads deals? Also, there are other ways in and out, there is that secret route into purgatory, so there could be others that would not be sealed by gates to earth being closed.

Even with the gates sealed, the demons would have all those souls to power themselves with, they could do alot of damage, even with travel deeply restricted.
