This is an excellent question.

I don't really have much of an answer for it, but one thing that comes to mind is maybe it has something to do with the Elven/Valar ultimate envying of Men in their ability to escape the Circles of the World. The Valar maybe persisted in giving the children of Elrond the choice because of their own (the Valar's) possibly growing desire to escape.
