The reason the satire works though is that this thread of paranoia does exist. I remember right around the first Obama election Costco started selling huge piles of emergency food in the stores, and I'd see people pushing caravans of carts down the aisle and pickup trucks and vans getting loaded up with 5 gallon buckets full of the stuff.

They still sell it, but only online, no doubt left over inventory from those days.

They even have versions for the opposite end of the political spectrum!

These are not quantities of food that one purchases for the occasional camping trip. This is Armageddon/Rapture preparation.

In case you have trouble getting safe water to reconstitute this stuff into food after the nukes fall or live uncomfortably close to Chernobyl or Fukushima they even sell radiation filters
