Where is all the Gold and Silver going to come from for this new "savior" currency that everyone is so sure of.

I am someone of the belief that we might need to use our bullion and junk coins for actual currency for a while. It seems like I'm in the minority when it comes to this as far as people on the site go. The consensus seems to be that the dollar will quietly and slowly dwindle away giving the government time to issue a "hero" currency enforced by the gold standard once again. I guess that seems like the logical solution since that's pretty much what happens in the currency cycle throughout history, and I do think eventually this is how it will be again. I just don't think it's going to bam here you go we're backed by gold again baby smooth sailing. Our Economy is so big with so many people (world wide) more than any currency debacle before. I believe it will be very difficult for certain governments our's being one of them to obtain enough physical to create an effective currency using the gold standard. So my question is to all of you who think the dollar will fade and gold standard will come right back when this happens is WHERE IS THE GOLD GOING TO COME FROM??? you can't just say ok we're back on the gold standard we have to have all the gold to back it up, and with our crumbling economy and unprecedented debt to other nations I don't see the transition being so easy.
