Here is how I see it. If I have cash...I have it in my hand....no one else has my cash in their hands!
Enzo Ferrari, when faced with financial obstacles in starting his company, tried to get a loan from the banks....no dice...screw you Enzo, is all he got.
Sooo, he started his own bank and financed himself.
I learn from history...from the Depression, to that shyster FDR, to Enzo Ferrari. I'm my own bank...operational Since 1970. No permission needed to borrow from myself, no paper work, no second or third party to get permission from....screw the banks!
I can respect this.
And there's something to be said for staying out of the system (as conversely there's reasons to be in).
But for the safety and convenience gained, there is the price of value erosion, which could be substantial over long periods or during shorter periods of high inflation.
We learned this after my grandfather's death, when we liquidated his property. My grandfather sold his butcher-shop after the war as a relatively young man, and subsequently worked as a union butcher until his retirement in the '60's, and was fortunate to live in retirement until he was 89 years old in the early '90's.
He lived through the depression and survived war-torn Europe. And with his not trusting banks, we found the entire proceeds and bill of sale for his war-era shop in a lock-box drawer in his two-flat, all untouched since the war! There was only 6 grand there, when a comparable shop in 1992 would cost around a 100K. (His two-flat, which was a similar building to his shop, sold for 97K in '92)
That made a huge impression on me as I watched my father's astonishment on finding the money, as we went through my grandfather's two-flat. My Dad was a banker who came from humble means, and he was all about growing the limited money our family had, so this really set him back seeing my grandfather had lost so much that could've been used by my surviving grandmother. We ended-up taking her in.
Ours is a more severe example of value erosion, but it is illustrative of the principle.
As an aside: He did have a few gold pieces and silver & gold certificates, which had appreciated in value.
Edit: O.K., you've since posted your preferred savings vehicle is gold & silver, so fair enough I suppose for your primary concerns.
