Granted, we all believe in food storage and having things on hand to survive a disaster or a power outage. However, I think sometimes the emphasis on accumulating things gets out of hand. We focus on stuff instead of skills. We don't think about the idea that we could be living without a lot of things.
If you are preparing for a long-term event, you can only accumulate and use things until you run out of them or have a plan to replace them eventually. You can keep a lot of food on hand, but you need a way to replenish the food. Most people will garden or raise livestock. You can only keep so much potable water on hand before you have to come up with a way to replenish that water. The list goes on, but eventually, we will have to find ways to replenish what we have or live without them. Our priorities will shift in a hurry to important things like food, water, and shelter.
