The use case I gave is: You lost your backups and your main, now what? You're done. Firesale on your life or business. Backups are something everyone has to contend with in any situation, but it isn't one that has been completely solved in the security industry yet in a way that is acceptable or uniform in any way. The average user just doesn't have a clear system for providing a high level of protection for both their security and ensuring they have redundancy in their life or livelihood. There are lots of different ways to skin a cat but no one has established a definitive solution or made it easy or obvious. Something like a YubiKey is only one part of a solution, and without something more you are at risk. Or, perhaps there's a way to create an encryption with redundancies built in so you're never in that situation to begin with. What if the concept of a backup was built into the key exchange and losing your original didn't necessarily lock you out.
