Granted it's a toy at the moment, and probably very inefficient, but it's still possible. Could I create one? I doubt it. Could the human ingenuity do it? We already have done, as a toy.

So the principles are still there for larger scales too.
I honestly believe that we would be able to cannibalise what we have long enough to be able to get a jump start. We already have picks, spades, axes, and the alike. So those by the mining areas would be able to mine. Then there will be those with the know how to start up a furnace. Blacksmithing would be easily doable. There would be plenty of materials available to start those kinds of things off.
It would probably take a good few years to get back to the year 2000. But I think it would take a lot less than we expect.
