Why do I think of the guy with a bitcoin collection that was worth $65 million, and when his computer crashed, he took out the hard drive the key was on, put it on the shelf -- anyway, he took the wrong drive, and through the right one away. Young man, not senile. Lost $65 million. If this is a "feature", it's one that will be used by the paranoid and the criminals. I'd much rather have a way of recovering my data. Cops can look through all they want, they're not going to find anything.
