Well, that's what I had in mind if you look at one of my (longer) posts above. But there is the problem that the Nine prolonged their lifespan, and as the power of the Rings was lost, they simply died. Nothing bound them to this world anymore.

Well, but the Ring was destroyed. It was not Sauron himself who had the power over the Nazgul, they were bound only as long as the Ring existed somewhere - not necessary even with Sauron. But from it the power stemmed. Like the power that kept Sauron "alive", even though he did not have the Ring with himself. So he could not control the RW after its destruction anymore.
