Sometimes the hard way to learn the lesson is the best way and sometimes a costly mistake by someone is an education for lots of people. It's an unfortunate side of human nature but it's valuable.
My own experience by proxy: A colleague of mine kept everything he owned on a single CDRW. It got put in a Pioneer slot loader. A few seconds later "boom" and the disk shattered into thousands of small pieces. He cried. I, and the 15 other people in the room, learned about keeping backups in multiple locations.
The same thing happens when a seal eats a penguin. Hundreds of other penguins learn to keep away from seals.
