Without a releveling of opportunity the inflated value of money will eleminate hard currency and create an electronic only money system. Just ramblings.
Electronic money is just as valid as notes/bills though. You have to understand: the money that you hold in your hand is imaginary. It's a PIECE OF PAPER. The only money actually "worth it's weight" is the penny (whose copper value is now in excess of 1 cent - it's illegal to melt them for the copper though
). Everything else - PARTICULARLY paper money - is essentially worthless on it's own. This is ever more true after we were taken off of the gold standard (before that the government had to have a certain amount of gold stored away for all the currency it issued, and if you wanted you could trade your money for that gold).
That currency only has value because we as a society believe it does. That's why the value can fluctuate so much. Electronic money (I assume you mean debit cards and such) is basically just the same thing under a different name. Whether we print it or not, it's still just a representation that we are giving value to based on our faith in the system.
I'm not much for conspiracy theories myself. I think that the move to electronic currency is coming, but I think that it's more a result of consumer convenience. I know that I rarely carry cash AT ALL anymore. In an odd coincidence, I saw my first debit-card equipped DRINK MACHINES today. Swiped my card, hit the button, and got my drink. It's just more convenient.
Are there some risks to that system? Absolutely, but that horse left the barn. FDR in 1933 took the first steps to take us off the gold standard, and Nixon finished it in 1970. No putting that genie back in the bottle at this point.
