The article sort of fell apart for me when I realized that only at the end were they making a distinction between prepping and hoarding. Now, I'm not sure whether they've been talking about "the management of stockpiled household items in anticipation of market disruption" or "being insane" the whole time. Which makes sense, because the question of whether keeping additional resources on hand in case you can't get them is reactionary or instinctual is a false dichotomy: you can easily reach the same conclusion in a lot of others ways. For example, by looking at history, or by looking at current events, or from sitting and thinking about what the smartest thing to do with spare resources might be, or by following the emergency preparedness guide provided by the government agency of your choice, just for starters.
