Then please abolish the upvote too. Because it too most often means "I agree". What you propose is a bad solution because it breaks symmetry. If people are upvoting because they agree (and if you agree you tend to think about the comment like it brings value), they should be able to downvote because they disagree. Overzealous moderation and self-censorship already makes HN too sterile place to be cozy. And similar to too sterile environments in real life it has a potential to weakening your immune system and cause auto-immune diseases.
