I think the answer has multple parts depending on the duration of the disruption. Most people would be hurting in three days. My household can function at subsistence level for two weeks with zero outside resources. Eat for six months given water. Defend life and property through any reasonable zombie apocalypse (I will run out of zombies before I run out of ammo). Hunt for a lifetime (including the zombies I would butcher cure and put by). But the long run answer is community solidarity. A combination of sharing barter and collective effort is the only thing that will get even the best prepared past a few months. Each of my immediate neighbors has a specialy or resource I don't have. Two have pools. One is a medium to large game hunter. Another is former Army, an EMT, and a more extreme gun nut than I am. My wife is a nurse. And I can cook gourmet roadkill. I will have to learn zombie cooking, though. But how tough can that be? Long pig, yum!
