Who's to say that out of all the possible stories from a zed appocolypse that many did not do what you suggest they should have. In this particular story, with these particular
characters, we have people that decided to hunker down, fortify, and survive the best they can, dealing with what they have at hand and not running off, despite the many challenges that would make that very difficult to do anyways, and not try to find someplace without having any idea of its condition. It's been said many times in the story that they could go somewhere else, but where? How could they know it'd be any better? How do they know they won't be followed, or that it's not actually worse there? Very early on they knew that this had spread everywhere.
