> But what happens when those heroes are unavailable? Maybe they're out on vacation, or medical leave, or they eventually retire or leave the organization because they're tired of propping it up? I don't know why people insist on using examples like this instead of the more obvious one: What if they are hit by a bus? Any of the other examples have trivial solutions in the event of an emergency: call them and maybe offer them some money. If they are very stubborn then go to their home and beat them with a wrench. But you cannot get information from a dead person no matter how much money or how big a wrench you have, and people die suddenly every single day. That's the worst case you need to be making contingencies for.
