If a comment or an item is worth a downvote, it's not a valuable contribution, nor does it contribute to the conversation. Replying to it then becomes pointless, and you are replying to nothing of value and something that should not contribute to the conversation. This would, as a result, make your comment equally worthless and equally devoid of value.
By commenting, you are suggesting that the comment does contribute to the conversations as its assumed that you would try to make your comment worthwhile.
You can't have it both ways. Either the comment is worthless and should not be read or replied to, or comment contributes to the conversation by at least sparking interesting and worthwhile followup commentary.
