That is Glorfindels and Galdors perspective, what people at the council were thinking was second guessing Sauron, it is Elrond who says: And those who dwell in the west would not recieve it, he also says: The westward road seems easiest. Therefore it should be shunned, only because that was the way the Elves always went. The Dark Lord expected one of the leaders of Middle-earth to appear on his doorstep, that would hardly have happened with the Ring sat in Valinor. Another point is that Sauron as one of The Ainur could know that The Valar would not recieve the Ring, or at least to have the same wisdom as Elrond in these matters.
