Two more thoughts -
One, I believe that the term “Hoarders” was meant in jest, or playfulness, by the OP. Nobody replying in this thread shows signs of the mental illness of true hoarding. So, ranting against people with that illness is misplaced.
Two, people who have lived through shortage, natural disaster, or uncertain times, tend to keep a bit more on hand. I used to live in hurricane country (to some extent, I still do), and shelves for essentials go bare before, and after, a storm. So, keeping some essentials on hand to weather the storm is simply being prepared.
Those who fail to prepare are foolish.
Those who have never experienced a shortage, natural disaster*, or uncertain times, are either naive or live in luxury.
*I’ll give you an example - in January, 1978, Connecticut was hit with a combination of ice storm and heavy snow. The ice storm brought down power lines and the snow made roads impassable for repair crews. The combination was so bad that the roof of the Hartford Civic Center collapsed under the weight of the ice, because the drains were blocked by the ice and snow from earlier in the storm.
We were without power for six days.
One month later, the Blizzard of ‘78 dropped nearly two feet of snow, and again, roads were impassable. The Governor declared a state of emergency, and roads were closed to private vehicles for three days. Stores, of course, were closed during that time as employees couldn’t get to work.
A “stash” of food, water, and fuel, along with survival gear like sleeping bags, flashlights, batteries, and camp stoves was not an indication of “hoarding” during those events, it was a matter of survival.
