It's difficult to have the resources to be able to do everything on your own.
Most people don't have a large enough garden to be able to have a section for grain. Especially since larger commercial outfits can do it very efficiently.
The smart thing to do is to find ways to store, for a long period of time, what can be purchased easily now, and have the capability to use it when an emergency comes up.
Accordingly, having a grain mill is a good, inexpensive investment, but it only makes sense if you also have grain. Some folks store wheat and other grains in sealed containers, and the larger sizes of these afford quite a bit of storage capacity. Among other things, they can be kept under a bed or in a closet.
If you want to be a little paranoid in your overpreparation, get a grain mill that can be operated by hand as well as with electricity.
In light of such thinking, it is my belief that home canning is an excellent preparation for security, independence, and for emergencies as well. Such prepared foods last for long periods of time, and do not require constant refrigeration for their longevity. One eventually gets into topics such as using pressure cookers for canning and such.
You will be able to find plenty of helpful advice if you wish to do these things.
I tell people, if/when the dollar crashed, FORGET precious metals entirely; you can’t eat gold.
GRAIN is the commodity that will be the medium of exchange for all else. If you think the world is going to hit the skids in any severe way, you’d best be figuring out how to silo a couple a three years’ worth of whole grain. It isn’t cheap, now; it’ll be flat-out exorbitant if things really DO get seriously ugly, and precious metals will prove to have been a total waste.
When grain is king, it’ll trade with gold on a pound-for-pound basis.
