Buying your way out of the apocalypse is a religion.
It's a pretty tempting one, too: I have to actively subvert that tendency in myself. When trying to get some first aid stuff for my bike, I was tempted to skip the research and just buy a first aid kit. If it's widely available, from a "trustworthy company", and generally looks like what I think I need, surely it'll cover my arse if I fall on it?
That's unquestioning faith in something you don't understand. But the issue is that these things aren't unknowable; they're uncomfortable to learn. Learning is hard, and complicated, and nuanced. To trust someone else who "learned for you" is easy. If they're right, you'll be fine. And surely they're right, right?
Right?
This mindset carries over to all sorts of apocalypses, big and small, inevitable or otherwise. Preparing for power outages, supply chain shortages, extreme weather events, and so on; all good ideas, all things I do to an extent, but that tendency is something that can be marketed towards. It's a tendency that can be manufactured.
Corporations are not your friend, or your God. They are not going to save you. Even the most altruistic ones will not grieve your absence, even if they're to blame for it. If you're scared, you're less capable of critical thinking. Remember who that benefits most.
Be careful. Run your backups. Fill your scripts a little early, if you can. Keep some money set aside for if your paycheck doesn't come in. Keep your pantry full of food that nourishes you.
Know what ways you can help people in your community, and whose help you can trust in turn. Survival comes in collective action and structural reform, not individualism and isolation.
Remember the most likely horrors are the boring ones, too. It's more likely I'll accidentally hurt myself mid-panic attack, than that I'll become an enemy of the state because my search history stepped on someones toes.
But do not let someone sell you your ticket out of the end times. It's a comforting illusion, but your imagination is cheaper.
