You say that not everybody can downvote, butyou forget to mention that nearly everyone can upvote.

A downvoted post needs someone to downvote it, and then for nobody else to upvote it.

People shouldn't downvote for disagreement, but they do. It's probably more important to upvote grey posts than complain about downvoting.
