Yep yep. A better analogy might be that the door has to eliminate quick, quiet entry to the house since that would deter a huge majority of would-be burglars just due to the vastly increased danger of getting noticed. We have locks on windows, but rarely bars. We have alarms that trigger sirens, but rarely indoor locks. Eliminate quick and quiet, usually good enough.
