She probably was killed, but took down several guards as well. It's more likely Crawford did not know that you turn when dead if the brain is intact, and were taken by surprise when the corpses they piled up assaulted them from behind.
I think the idea to keep moving is better, unless you can find an area like the Alexandria Safe-Zone in the comics. Supplies are not endless, and staying in one area will deplete them eventually. It will not matter if your fort is impregnable if all the walkers have to do is starve you out. Farms could work, but not everyone knows how to farm, and i assume farming isn't so simple that anyone can just plant seeds and instantly be successful.
You would probably need at least a fairly large group to start taking back areas, and you'd also need ammunition for weapons, which is also not an unlimited supply. Survivors could switch to melee of course, but that poses a constant threat and could cost lives every time the walkers are cleared out. Everyone makes mistakes, and even the smallest may cost you your life in this scenario.
There is also the human threat, of course. If your perfect sanctuary happens to live next to a large bandit encampment, then you're going to have problems.

Like the prison in the comics. It was well fortified, but because it was close to Woodbury, nearly all of Rick's group were killed as the prison was stormed with a tank and an army, and the survivors were forced out.
The biggest problems to staying in one place are the lack of supplies and opposing human threats. It's just safer to be on the move, at least initially.
