A cashless society using electronic money can easily be achieved through a gold standard. Trust me, I'm not pumping gold, per se. But I would love to see a gold standard come back into to use and an end to the constant inflation for the enrichment of the banksters and politicians.
But what it really boils down to is, the worlds financial systems are FUBAR. The central banks are going to QE the world back into the stone ages rather than admit their fiat money experiment is failing and has failed. After that, what's next? Here's a clue, the golden rule...he who owns the gold rules. And who has been buying gold hand over fist? All sources point east, and not just for jewelry. And I'm talking physical, not the paper gold market that crashed.
What the eventual outcome will be is still to be determined. But it won't be good for fiat, that I'm very sure of. Unless it evolves into fiat backed by something of greater value than the paper it's printed on and the word of the lying governments behind it.
BTW, the sources for those articles are easily verified, if you want to take the time.
