Tell THAT to the ant, thou sluggard.
Since I know your question is sincere, and the thread isn't currently busy with the OP, I'll try to answer it in general, at least.
Food... always figure 2 years worth. Obviously, that doesn't mean being able to eat the diet you're accustomed to for 2 years while the world is in chaos... but as a farmer who has grown nearly all our food for over 40 years. I know you're always going to have a "bad year" for some crop....maybe more than one. Staying a year ahead on everything you can for storage (and if you think you'll have a way to keep a freezer running, you can keep fruits, veggies and jeats for at least 2 years, if they are vacuum packed and sealed)
By the end of those two years, you should have managed at leasat one crop, and move on from there.
Additional insurance against famine used to be cheap... my beans and rice were purchased at 50 cents and 19 cents a pound. Pasta was 30 cents a pound. Now... not so much. However, a packet of seeds for a couple different dry beans, and a 20 foot row can produce several pounds of beans. If you mulch heavily once they are sprouted and growing, you'll have few weeds to contend with, and less chance of getting mold in the beans if the pods rest on the mulch.
The more variety you can keep in your preps, the better off you'll be.
Our priority list:
Clean water
Sufficient food to provide needed nutrients for 2 years for each person
All the tools needed to continue to heat the house (and cook food, once the propane ran out) for at least 2 years
Sufficient boots and shoes for everyone
Adequate sturdy household necessitues.necessities.. everything from kitchenware to sheets and towels. I actually started this in my early 20s when I chose stainless steel mixing bowls over plastic or glass
Adequate sturdy clothing for all seasons. If people in your group have weight issues, you may have to plan on altering their clothes, because most people will lose weight.
A way to heat your house, and get water if you can't run a well pump
Medical supplies to cover minor to moderate problems. If things go badly South, people who suffer serious injuries or illness aren't likely to survive.
Once you've got the above covered (obviously, I left out a ton of details... garden seeds, hygiene items, personal protection), THEN youncan consider more than a nominal amount of PMs. I'd suggest *everyone* include a roll or 2 of pre-1965 dimes or quarters... to be used in a dire emergency, only (buying gas on the black market to drive someone to medical help, for example). Putting enough cash into PMs to cover the next 10 years property taxes probably will pay off in your favor.
But above all... ask the Lord what HE wants you to prepare for! Our Amish friends considered prepping close to sin... relying on your own plans and "wealth", rather than God. They also pointed out that we don't know NOW how long our lives will be. It's all God's will.
