You are arguing, I imagine, that [strictly speaking], "casting a vote
which prefers option A over all other options" when compared to "not
casting a ballot at all" is not an example of "voting the candidate

If not, I'm not sure how what you're asking relates to the monotonicity

However, if that is what you are arguing, I suppose I could see some
justification for defining some different criterion to deal with the
case of "I voted for X so X lost, where if I hadn't X would have won".
However, I would say that this criterion is probably even more fundamental
than MC.
