Perhaps something else to consider is the sheer versatility of one pot for cooking in. Using a wood fire, I can literally cook any type of recipe I could do using all the other cooking utensils in my modern kitchen. Using my 12" deep camp dutch oven, I can roast, fry, parboil, or saute any meat, make crepes, pancakes, omlettes, muffins, coffee cake, any type of quick bread or yeast bread, or flat bread, boil, fry, saute, roast, or bake any sort of vegetable, make custards, quiches, puddings, jello molds, aspics, pasta, rice, beans, casseroles, souffles, cobblers, pies, cakes, doughnuts, cookies, brownies, jams, jellies, syrups and sauces. All this from one pot and a wood fire and a few mixing and handling utensils.

If you're in a shelter in place scenario without any other modern utility based heat source, you can at least build some sort of fire and use your cast iron pot.

Incidentally, the list above also represents just about everything I have cooked in my cast iron dutch ovens.

Oh yeah, they boil water pretty good too.
