I've found this Q&A for powerful people
Most of the terms were a bit absolute in their power (godlike, big-brother, etc.)
What I'm looking for is a word that could be used to describe anyone from a head of household, to a loud voice on a committee, or a creator whose project has outgrown them but they won't let go.
The concept is that they are an authority and they refuse to let things change.
Imagine a very old person who sits on a board, has completely lost touch of time, and keeps trying to make things stay the same.
Is there any single word/term for this?
My friend suggested "justice scalia" as a nickname for this type of person. I'm hoping for something less colloquial.
Example sentence:
Old Taylor, the head of the HOA, is ridiculous for not letting kids skateboard on the sidewalks. I've tried my best to go to the meetings and talk some sense into them, and even as everyone I know agrees that kids skateboarding on sidewalks is fine, old Taylor refuses to budge. It's too bad they've become such a [WORD FOR STICK IN THE MUD OBSTACLE ON PROGRESS].
