Question: Why didn't the elves let everyone go to the undying lands? That way no one would die from Mordor's armies. In fact everyone would be happy there.

Answer: The Elves had no say in the matter. The Undying Lands were created for the Elves by the gods, who decided who was allowed in; the only non-Elves allowed were Bilbo, Frodo and Sam (as Ringbearers) and Gimli (due to his participation in the Fellowship and friendship with Legolas).
