  The common mistake with signing schemes is assuming that it actually means anything on its own. There is no need to it. That would only make sense if you want to mark something as offical and have authorative sourcing. It would have a place for chains of command and actually signed off on orders but not evidence that the content is true. An offically signed video of the president punching Adolf Hitler in the groin, High Fiving George Washington, and then flying off into space could be cryptographically valid although obviously fake. It would only say that the President actually approved this but not that it was real.
