Okay, here is the difference between two different kinds of storage and thus stocking up vs hoarders: "Easily Accessed Storage" vs "Static Storage." This concept of storage is from the book, Banish Clutter Forever. I didn't write down the name of the author.
Easily Accessed Storage: is a place where one stores stuff to get to easily. It is stuff that is USED and being depleted, (even if replenished often.) So things are stored
temporarily. This would include stocked up items. Also items that come out every day to be used, like kid's crayons in kindergarten. They come out, they get used, they get put away again, they get taken out and used again, etc. Rinse. Repeat.
Static Storage: is the kind of stuff that will stay in place long term. Stuff that usually goes up in the attic, the garage, a storage unit. And rarely does one go into it to get stuff back out. Maybe once seasonally.
For
hoarders, stuff goes in, waaaay beyond what they need or will use, go through, or deplete. The stuff basically never comes back out. This is when their "stockpile" becomes a hoard. It's ALL static storage to the extreme.
We are all in very unusual, not normal times. Unless someone's been through World War II and the like, where they also had to stockpile and ration stuff, most of us have never been through it before. So we don't quite know how to do this. How much to get? How much to have on hand? How much to keep? will it all get used? What will the stores be like in a couple months. etc?
We all have different situations. Some of us are in highly infectious areas. Some are high risk or have family members who are high risk. Some live in areas where supplies just aren't plentiful or easy to get to during "normal" times.
Many of us are probably looking at and gathering items and wondering if one is stocking up or hoarding,
even without the social media shaming and guilt tripping.
When one is looking at items wondering how much to get, it would be prudent to ask when is the next time you are planning to buy or order again? How much will you realistically need until then? How much is available for yourself and also for others?
If one is grabbing canned foods that will take them 5 years to get through, not leaving enough for others, even if they will be in the store again in 2 weeks or a month and can get more cans then, then YES, it is too much. The cans will also have actually expired before then and have to be tossed. It's hoarding.
