If you need to buy or barter for something, even if for very high value, you can find someone who will give you what you need for your gold. At this moment that is not true for Bitcoin. Sure there are people around who will do some trades for your BTC, but not that many, nor in large amounts.
I'd quess the number of people that will accept BTC at localbitcoins.com is roughly the same (within an order-of-magnitude) as the number of pawnshops in the world that will take your gold coin. Here in the Philippines I bet you'd be lucky to get 50% of the spot price value at a pawnshop.
The key difference in my mind is that gold you can find a physical buyer that you can trust won't kill you (e.g. a storefront pawnshop or gold dealer). Whereas meetups with Bitcoin are going to be with a stranger (and risky for both parties). This is important in the sense of needing to get cash and not wanting it to pass through a bank account.
Once the NWO outlaws cash (and regulates gold dealer, but the lack of cash will kill the black markets too), then there will be no advantage for gold any more. You will have to sell it for digital cash. Barter becomes extremely rare to find.
OROBTC, I am sorry to tell you that gold is dying. The digital cash age will kill it and everyone will throw their gold into the streets as the Bible says. We may not get there entirely though until 2032 or so.
