It's a good analogy if the reader understands it, and it is accurate.

Both are true here. People don't get away with quite that level of nonsense with buildings because even laypeople can see all the essentials, why it would be bad, who to blame if it did happen, etc. So it never happens and doesn't need any kind of illustraing analogy to explain it to anyone.

That DOES happen all the time in software and it's invisible to almost everyone including your own bosses, and does need some kind of analogy to illustrate what's wrong about it, and how wrong, and the nature of the wrongness.

Any other example that actually ever happens, would just be some other equally opaque phenomenon from some other esoteric field, and would by definition be useless as an analogy.

The whole point is so that anyone can see it and conclude "that would be crazy, outrageous, intolerable". Of course it never actually happens.
