No real-life system is ever engineered with zero margin. Ever.
Not deliberately, anyway...
I never read that, but I was taught very early by a teacher I really trust that 2:1 overdesign is still risky; we don't know everything, nor can we reasonably expect to find out before we build it. Really important items are overengineered as much as 5:1.
ETA: Actually even that's an oversimplification. Try this:
We need a directorate of science, and we need it to be voted on only by scientists. You don't get to vote on reality. Get over it. Elected officials that deny the findings of the Science Directorate are subject to immediate impeachment for incompetence.
