Pure cash is redeemable in probability of arrival

Those secure digits we pass around, they are place holders in the various queues that deliver goodies to our hands.

So, our judicious use of secure digits means we can guarantee, almost to a sum of one, what the probability will be that good a arrives within some n transactions.  This is what the economy is made of, queue management. More valuable information cannot be obtained anywhere, but we have to have secure digitsm shipped around at near zero cost.
