1) Racing to home would be too late for anything non trivial. Infrastructure will be clogged to no end. Likewise ham radio and most forms of communication. What good is a phone charge when the network is dead? That's a nonsense preparation, like many kinds of bug out preps. What good is a bunker if you cannot get to it? 2) Lack of provisions will immediately hit everyone and looting will ensue, like in New Orleans. Cash becomes worthless due to looting, like many amenities and luxuries. Barter economy takes over and the main bar items are food, water, heat sources, tools and weapons. 3) Agencies are glacially slow to activate and their response is limited. 4) Even if you do have a gun, so do others, alone you're not even important compared to already organized crime and paramilitaries. Or people with private militaries like top government. 5) If water or electricity fails, there is another degree of bad on top. Most people are not prepared for this. 6) Some people think they can outhunt such a problem, this is stupidity. You cannot outprepare anything this magnitude. Even with specific civil defense knowledge and resources you have few chances and a definite shortage of provisions. Long term plan always relies on farming and banding together. Specific tools and knowledge for specific problems, such as efficient gathering aka looting, building, maintenance of infrastructure, true people management skills, loyalty, useful connections. People with health problems get instantly shafted, even some really rich may have trouble. The default is never individualism nor democracy. It's almost always feudalism or tribalism. Small to medium polis caring for its own local problems. Few hundred to few thousand people. We know much more about it because we have a semiregular flood emergencies in places in Poland. And those are relatively small fish where standard social structures do hold up. Likewise places hit by tsunami or bad earthquakes. Cheap Africa level affordable, reliable and reusable solutions are the way to go... something completely in the face of consumerism.
