Ahh, money... For me, money really plays three roles (I did not come with this, but this makes the most sense to me):
1) Money should be a Unit of Account, a measure of how much something is worth, currency is good here.
2) Money should be a Medium of Exchange, you give money to someone for something in exchange (currency is great in this role)
3) Money should be a Store of Value, worth about the same a month, a year or a decade from now, currency is NOT good at this.
Therefore, I would like to see a different "system" (for lack of a better word at the moment), where something like gold is freed from its role as "backing" a currency. Why should gold back anything? It is its own worth, an independent value vector if you will (as an asset or investment). Gold is the best Store of Value, and has been so for 6000 years. NO currency has long survived...
Currency for marking value and conducting transactions, gold for store of value. Currency cannot perform all three roles of money.
Currency != Money, as it fails as a Store of Value.

The division between money and currency is IMO an artificial one but feels so natural because it has gone on since the 1600s, and only stopped (though some say not really) in 1971. Physical gold and silver served fine for all 3 needs before that, and explicitly risky assets like credit served to drive growth.
In an ideal world, money should be money, and debt should be debt. Since the elites created what was really a form of debt, but which they successfully passed off as money for a while, some of us were forced to develop a new concept, currency, to describe this world.
Gold backing of currency has always been a tool for the elites to prop up the value of their paper 'money', whatever their public-relations organs (read: professional economists) said the purpose was.
There is a (probably growing) voice among the elites which wants to go back to precious metal backing of currency (and thus back to the dual existence of money and currency,) though the backing may take a more sophisticated and modern form than the classical metallic standards. (See India's new gold-bond system for a peek at that possible future.) Not to spur any conspiracy theories, but your reference may be in line with this voice.
If it happens, it would probably be a little better than today's world, since metallic standards in any form do slow down financial inflation, but it wouldn't be essentially different from the elite-designed system of exploitation of today or the metallic-standard periods. Only the elites would ultimately benefit from this system, besides those few of us who get into precious metals early enough.
