The post-apocalyptic economy is kinda borked

with the way people are hoarding people are hoarding toilet paper and milk, instead of medicine during coronavirus, never underestimate human stupidity.
Its just like P. T. Barnum said “there’s a sucker born every minute”
Plus with no functioning factories batteries that can power live saving gear like blankets and flashlights become much more valuable.
After all bullets are just one use items, so why are they still valuable?
The thing about economy isn’t that its understanding how valuable something is, its understanding how people think something is valuable.

Just take diamonds for example: a useless and easily found rock that still costs hundreds because of sentimental value.
