No, no, no. This is why reasoning by analogy can lead you astray. We have enough control over the world of software that the problem described above should not exist. This control does not exist in the real world, but it does in software.
Do we have enough control over software to make it impossible for someone to delete something and make it unrecoverable when they will later realize they should not have done so?
Not impossible, no. But we absolutely have enough control over software to make it highly improbable for someone to accidentally delete something important and make it unrecoverable.
