The problem is that down-votes have account consequences. They aren't the mirror opposite of an up-vote. Ten upvotes and a post is just popular, ten downvotes and you might get banned.

If moderation was a flag that some people cared about but that left everything intact then people could ignore it if they wanted.

Do you think you get banned for the downvotes, or for the comment? I don't think anybody (here) is proposing removing the "flag" button...
