I'd say gold could be down to 850 aud by June 2009, but then climb the charts to something more like 5,000 aud in 2013.
I.e.: they can buy/sell it whenever they like in relatively unlimited volumes (exchanging it for printed money),
Governments cannot sell gold, because they have none of the real stuff anymore. This only leaves one option, exchange unlimited volumes of paper money for it.
The trick is to make it volatile, so it won't be seen as money. The ultimate trick is to corner the market and "fix" it at that measure in the boss currency.
Don't short it after June 2009, you'll only reget it.
The only useful thing about oil, is it make a vast amount of material wealth possible. Humanity can turn their back on it.
simply prohibit to own the gold.
In this rebellious age. What would they use as a justification?
