This concept would be more useful if you promote a "monetized" currency that sets an international standard for coins and bars composed of a specified weight and purity of useful metals. With this information stamped on each minted item, you could have units of one, five, ten, twenty, one-tenth, one-quarter, one-half, etc. and it would not matter whether the coins are manufactured by a private entity or governmental, or in what nation.
The wealthy would still have to deal with notes and depository receipts, but the 90% of us whose wealth would fit in a glass jar could stop worrying about short-sighted legislatures ruining the value of our savings.
