you haven't said much about what the labels on the canned goods should read, My thinking, they should read, maple leaf, krugerrand, eagles, and a case of yuans.
I would love to hear your thinking on the preservation of assets.
there are lots of books on how to protect your assets from society's meltdown. The problem is that they all work from a set scenario of the author's choosing. While there is always something to be gained from prudent planning there is the "best laid plans of mice and men..." factor to be dealt with.
Knowledge is the one thing that can't be taken away from you and the only real safety is in numbers. That being said you might be able to gain more friends in a real crisis if you can feed them, than if you have a safe full of Krugerrands to trade for a loaf of bread. Still, I would act prudently in regard to any assets, you can't eat paper either.
