Misses the mark. The motive for stupidity is corruption, hence the exercise of power. An anonymous unidentifiable third party gains from it and you are to pay for it with obstruction (active attacks are rare). By definition you don't know if it's corruption or stupidity, and that's why stupidity must exist, as unmotivated corruption, meaning it's just a part of the person or organization, for example ideology. Stupidity then tends to equate to incompetence. But to the observer victim there is no difference.
