After reading this article, I want to stock up on more food for myself and my five dependents. Double our reserves of biscuits, cereals, frozen meat, frozen bread, canned food, preserves, long-life milk, honey, multivitamins, MREs, etc etc. Is this panic buying? Is it OK? Does it hurt other people? I’d be interested to hear some different points of view.
But don't panic buy. Don't now go to the store and stock up massively. Put in an extra shelf-stable item, and next time you go shopping do it again, but don't panic now. That's how you create a food shortage.
Even if you add "only" 10% extra to your purchase, I think that's what happened with toilet paper. I purposefully didn't buy any, figuring the crazies would get their fill soon enough, but a month later it was still going and we were trying not to be in the store more than once a week to prevent that being a spreading place but could now only buy 2 rolls at a time per family and many stores were completely out. Of course, we didn't even have to ask neighbours yet (some neighbors will have had to spare, not as if the rolls all disappeared into thin air) so it wasn't bad in any way in the end, but this panic behaviour is unnecessary and very quickly detrimental, even when a majority of people understand it's unwarranted.
