I would guess this is a consequence of people following orders. There's many people that should have refused the work along the way, but only the planner gets the blame, while I'd bet the planner was only following orders also.
People need to be able to think for themselves. I once stayed in an apartment house where I noticed a door 1.5 m up in the air on the outside of the building. When opening the door there was a small bathroom with a toilet. With no way of accessing it from the inside. Just that normal inside door on the outside wall up in the air. 100% someone in the chain made a mistake and said the door should be on the wrong wall. But no one that actually built the house stopped and say ”eh are you sure?”
