"Why in the world would anyone [X]?" comes off as starting with a strong opinion that [X] is a bad idea, rather than actually asking for information about motives.
Better?
In any case, as we discussed below, my original interpretation was that this is about the general desirability of [X]. I also obviously implied I've heard strong reasons against [X] but few convincing ones in its favour.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
