These numbers seem off. Is this world GDP? US GDP is only 17.

Where did u get these numbers from?

Also I think future liabilities are not too relevant since they don't have to be paid.

The other issue I see is that currently gold is unlikely to become currency again as such your entire business case makes only sense if there would only be one choice.

You would have to factor the %age of the likelihood in there somehow.

But thanks for these numbers, again could u let us know where u came up with them?
