If the bad guys storm my house (which us what the OP implied), I am not going to get out the back and leave my wife, who is an invalid. You can haul ass if you want, but such a measure is not on my radar.
Key words are “if you can”. In that situation of course I would make my last stand at the Alamo. I will do what needs to be done to protect the clan, but the best strategy is to not purposely box you and yours in if there an option to get out and mobile first.
