Those who can, DO!
Those who can't, Teach.
Those who are clueless, make the rules.
The further you get from knowing ANYTHING about the subject, the more likely you are to have the power to enforce your rules. And the harder it is to challenge your "Rules".
Sadly, it's a fact of life. Case in point: I drive an ambulance that is REQUIRED by law to carry a 5 Lb sledge hammer & a crow bar "For use in vehicle extrication". Ive been doing EMS just shy of 30 years & have NEVER even seen their use demonstrated. For vehicle extraction we just use the "Jaws of life" (a copyrighted name BTW) or similar product. I can open a car in about 30 - 60 seconds once set up. Yet, the (Indiana) law requiring the hammer & pry bar is still in affect,
& will be in the foreseeable future. The law makers haven't had to get into a damaged car for rescue in over 30 years, IF they ever did (Which I doubt), yet,,,,,,,
