JH,
I am pretty much in agreement with your views and don't feel this is introducing something new, but removing a delusion which has developed within the process. Even a gold backed currency, as opposed to using gold directly, is a contract. As in 'IOU an ounce of gold.' If it was hard, ie, the value directly tied to the amount of gold in reserve, it would not be stable, because there would have to be a constant adjustment of prices, relative to the size of the economy, versus the amount of gold. So on the other hand, a stable currency would mean it would not, in principle, be hard, because there would have to be shock absorbers and only in the event of a severe crisis would the amount of gold be relevant. Then the powers that be will find it necessary to deal with the discrepancy, which was the situation in the 30's.
The problem in the system as it is, is that everyone thinks they need as much money as they can get their hands on and since it is a commodity, this isn't a problem for the functioning of the system, since we all have our bank accounts, but it doesn't work that way. This mostly serves to empower the financial services industry and requires them to create massive wealth storing devices, ie. 'derivatives, securities, options, etc.' which further empower those with the most wealth, in a feedback loop that essentially drains value out of other parts of the economy and amounts to a large tumor on it. Think of it in terms of blood supply; The brain needs and gets much more than the feet, but it doesn't get more than it needs, or you have a stroke. Similarly, if the feet got significantly less then they need, you would lose them. Now, rather than people thinking of money as some material property which can be harmlessly stored, if they really understood it to be a contract, a bookkeeping entry, where one's asset is another's debt, there would be a much greater appreciation for how the larger economy is fundamentally tied together and harming one part unnecessarily creates negative blowback for the entire system, etc.
So it's not like things are going to change before they all blow up, but after that happens, this might just be one of those hard lessons we need to 'take to the bank,' if we want to build back up a viable world economy on the significantly less resources remaining, then we had to build the current one.
And I am back out to work....
