When almost any voice can be generated without a person behind it, most people will not become better at detecting fakes. They will simply trust fewer new voices. The ones that remain useful are the references they already know how to return to. A .eth name is one such reference. It stays under the control of a specific person. Work, statements and history can be attached to it over years. Anyone who wants to check later can come back to the same point without depending on a platform to keep the link alive. In a landscape that produces more content than it can verify, the names people already remember become disproportionately valuable. Not because they are flawless. Because they are still there.
