It is not that simple. If an economy has a surplus, e.g. China, where does that surplus go? This is why we have a default world currency whether that be silver, gold or petro dollars.

When you work through it a bit more the more you realise a basket of currencies won't work, unless every currency is essentially the same. Capital is like water, it flows.

I would like to see discussion on how we can move on from the currencies we have to a measure of energy. Everything can be measured in energy terms, why not cut out the abstractions?
