Although I agree with what you said about the downvote especially in terms of readiness. You must be aware that there is a difference between downvote and flagging content. The downvote is one where you disapprove with someone's opinion and cancel part of his vote or all of it based on your power. The flagging option is a feature that is used when you find abusive content which in turn lowers someone's reputation and visibility along with potential prize they would receive.
