A closer analogy would address a group controlled by a few which has the resources to install people (whom believe that are doing good things) into positions that have access to your private keys. It's more like there is an automatically updated encrypted manifest of your house available. The bunker analogy is bad unless you think we should meet in the middle on infosec. At some point, this same conversation will be about hardware inside our heads, we already use these devices like second brains.
