The psychology behind toilet paper panic buying

Okay, I understand that the distributors' warehouses were not stocked up. I'm also hearing that we have plenty of food in this country, and it will be delivered to where it needs to go, and no, grocery stores will not close down, people will not starve, etc., etc. I'm also hearing that truckers are working day and night, having trouble finding food due to the way various states have shutdown the rest areas & places they normally would be able to eat.

So where's the food? And toilet paper? And paper towels? And hand sanitizer? And sanitizing wipes? And dog food? It's not on the shelves here in the heartland.

I'm feeling lied to, and like there's something conspiratorial going on - not that the coronavirus isn't a real thing, but that it's being exploited for someone's agenda, which is hurting Americans.
