The idea of "safeguarded savings" is a conceptual abstraction. Think of a barter economy. I trade you a loaf of bread I baked for a haircut. Where did we get the idea that I should be able to bank that haircut, and come to you 10, 20 years later and still get that haircut? It's a view that comes from seeing money as something of intrinsic value, rather than what it really is: a proxy that decouples transactions in what would otherwise be a barter economy.

In nature, "savings" are subject to loss and decay. You "save" by building a house to live in or storing away grain--all those things are subject to deterioration, disaster, etc. Financializing it doesn't change that underlying fact.
