Having a high reputation shouldn't be a free pass to be an obnoxious jackass, but often that is what ends up happening. There is virtually no consequence to coming into a valid question (or answer) and just close it like a dickhead. No, in fact this behavior is rewarded.

If you are either someone who likes wielding power recklessly or autistic then becoming a power user isn't a problem. But demanding users "prove" they are trustworthy in a system where blatant abuses of authority go unchallenged is farcical.
