Communication. Some languages require the emphatic multiple negative. My point is that the emphatic multiple negative is more understandable than the logical multiple negative. And my example of the logical multiple negative should have been "I couldn't fail to disagree with you less."

If you can handle a language so corrupt that the adjectives don't agree with their nouns in case, number, and gender, then you can handle a couple of spare negatives scattered about here and there.
