"Once again, you are confusing a floating currency with a company using a blockchain technique for more transparent and safe book keeping of their gold inventory."

You're purposely ignoring basic economic principles required to understand the gist of my comment. Spend some time doing day trading in the metals market and you'll see how a blockchain isn't going to help with keeping gold inventory straight when the prices are tied up. This is gold settlement, not simple inventory tracking, so this is a much more complex issue than you're trying to make it out to be.
