I generally agree with you, but there&#x27;s one problem with the physical key analogy. The security of physical keys is weak enough that there&#x27;s always a fallback if you lose all the copies of your key: you pay a locksmith to come pick the lock and rekey it.<p>You can&#x27;t do this with digital keys because a digital key that is weak enough for this strategy to be usable is also too weak to protect you from the main class of attacks it&#x27;s supposed to be protecting you from.
