For meta titles and descriptions to have any impact, they need to be in front of a user's eyes.
Are you suggesting that nobody is seeing organic listings? That sounds pretty farfetched to me.
By maximizing clickthroughs from the search results that searchers do see, you help to make up for the search results that searchers don't see. You can't make Google reduce clutter on its SERPs, so you might as well try to make the most of what you've got. IMHO, that makes a lot more sense than just complaining and giving up.
