That potential revaluation of US gold assets to market value is extremely interesting.
More 'outside the box' thinking.

Seems like a pretty reasonable thing on the face of it;
in fact it seems quite odd that the current valuation is $42 /oz, but
from my understanding, where this might become problematic is that it weakens the Fed's powers.
They would end up owning only 1.5% of Treasury's gold.
Currently they own ALL the gold.
Here's a discussion on how this works, from a few years back.
