Ah, but where it explicitly said that it was only the Rings that kept them bound to the world? No doubt they had the function of turning them into wraiths by streching their lifespans and making them reject the call of death. But once they'd become wraiths, maybe they had reached the point of no return and could no longer leave the world? In that case, even the destruction of the Rings wouldn't keep their spirits from haunting the earth. I know I'm streching th lore a bit, but it's a possibility.
