I think many people mis-understand locks. Locks are very rarely there to prevent entry. It's there to prevent undetected, unauthorized entry, or to make entry a little harder, but not impossible. With bump-keys, most locks actually fail at both (never mind lockpicks) -- and end up being a strange kind of security theatre -- where most people are in fact actors (ie: don't realize that so many, many locks are completely insecure in any meaningful way).

Another thing that people often mix up, are security and safety. A secure door/building is a death trap. If people can't get in/out in an emergency, that's usually terrible, for almost any kind of building. A building that you can't break into or out of in less than a minute, is unsafe.

Or to put it another way: what's the difference between being in prison and living in a castle? ;-)
