Brian:

Some very interesting comments. However, one thing for the group to think about (and I will apologize in advance if this has already been brought up but I missed it because I have not read all the comments) is the issue of population and die-off. My very superficial appreciation of the population I come into contact with on a daily basis is that there are many many many individuals who have none of the right skills and would be hard pressed to come up with any other abilities to survive than those of functioning as a parasite. My fear,should money ever 'disappear' is that the parasites of society, i.e. drug dealers, criminals of every other ilk, etc. would find themselves in a tight spot, having no abilities other than the inclination to suck off of the rest of society. I fear there would be a period of absolute chaos with much loss of life and suffering. aBarter would be one way to survive, but what if you hve nothing to barter?
