> Is there some big idea I’m missing that explains the favoring of the “mutable past” view? It is called law. There are lots of laws that govern circumstances under which data must be destroyed, and others that make certain data illegal to possess. You can argue that they're bad laws, and I'd agree that some of them are. But whatever you think of them, ignore them at your peril.
