Everything sounds like a good reason in a vacuum. I could write an equivalent appeal to emotion justifying why retaining walls ought to be engineered but the fact of the matter is that a bunch of barely literate people working from reference tables managed to do fine and copying them probably will do fine too.
I don't think the chassis of my dryer becoming energized is a provably satisfactory outcome.
I agree that a lot of code amounts to bureaucratic nonsense, but many rules were changed over time for good reason.
