Hi doma,
I think the central bankers have done more good than you think, but then my jellyfish economics tells me to grow the economy (using money and government projects if necessary) out of contractions and to shrink the economy (limiting borrowing and not replacing government projects) out of bubbles.
Unfortunately, the Bush administration had this thing called supply side economics, which encouraged major government projects (also called war) and borrowing oodles of money (to fund tax cuts) during the bubble years. Exactly the opposite of the right approach. With the catastrophic result which Obama and Bernanke are still working at fixing.
By comparison, David Cameron persists with inside-out economics: austerity during a crisis. So you see the UK struggling with unemployment and growth relative to the US.
I am not sure what kind of economy gold bugs imagine working. They believe in catastrophe, but I don't see them producing an economic construction which can operate a modern economy. I see dependence on a debaseable sort of currency as an unimpeachable virtue. And then ...?
With your view of an electric universe, I am surprised you don't see energy as the base unit of value. Oil generates power (which may be converted to electricity). Same goes for sunshine, algae and wind. These things are useful. Why not trade access to them as currency in doma-world?
