Lean Manufacturing consultants talk about "Just in Time" inventory but never define what that is. If you push for a definition they will say "all inventory is bad". I like to call this Abstinence-Only inventory education.
Doomsday Preppers have enough items on hand so they can start a new life without any input from others. This might mean food stores, or equipment to rebuild a whole society.
Which of these suits you more closely? The best answer is probably somewhere in the middle.
