It's a little more complex than this, I think.
If someone knocks on your front door, that's one thing, but what if they
start checking your back door, side door, garage door, windows, pet
door, etc? Is it appropriate to attempt access through ports not
normally considered access points?
For another example, lets look at a business. If you walk up to the
door, try to open it, but find it is locked, no problem....the store is
closed and you walk away. However, is it appropriate for you to try to
enter via the service entrance in back? What about a window? If you
find it is unlocked, is that clearence to go in?

Either too simple, or we're just trying to stretch an analogy too far.
