Proper prepping prevents panic.
It’s never a bad thing to have 4-6 weeks of food you eat (or would eat) stored at home. Store what you eat, eat what you store. If nothing else and you’re a ‘eat out most of the time’ kind of family, keep your stored food/supplies rotated and a cpl months before things expire, donate them to a food pantry or church.
Panic is what happens when something bad occurs and you have no food in the house, or just a half full styrofoam container of what you ordered in for supper last night.
I agree with the need to prepare for any event that may cut off regular supply of essentials. However there are plenty of people who assume being told to be prepared means there will be (not could be or might be)a worse case scenario and instead of going about things sensibly they panic buy. Stores may want to start putting limits on per person purchases of certain items. To make sure hoarding of essentials is avoided.
