you mean, like having people to remember to bring their house keys when they leave so they can get back in? Yes, it's an extra step that has nothing to do with

  That's a really decent example, because if you forget your house keys, you aren't forever denied access to your house / your house doesn't collapse into a shower of noise, never to be reconstituted. If it did, you can pretty much guarantee people would either stop using house keys completely and just leave the key in the lock all the time or would come up with schemes to make it impossible to lose the key (such as locking the key in a tiny box, and then that box is secured with a key that doesn't cause the box to burst into flames if the second key goes missing). In non-digital life, we make the tradeoff of less-than-perfect security for convenience, backed by the law (i.e. any competent locksmith can break into your house, and the things that keep them from doing it are (a) a general societal understanding that cracking open someone's front door without consent is a really dick move, and (b) if you do it, you're trespassing and can go to jail).
