On the other hand, there is likely also a local maximum where the premium is fairly small. In this case you get not only all the people above, but a large percentage of the people who are willing to pay just a little more for privacy.
As to where these local maxima actually are, and which yields the larger profits, I have no idea.
It all boils down to Bedford Forrest's maxim "Get there first with the most men." (Sun Tsu said it first, but Forrest probably wouldn't have liked to know that, I'm sure) If in fact there is no method for making cash transactions on the internet, particularly "off-line" transactions with no trusted third party in the loop at transaction time, then digital cash is all we have. Eric has destroyed the point about the efficacy or need for off-line transactions already, but to expand on his last sentence, there needs to be empirical evidence to back up or refute his and my opposing claims.
The costs associated with anonymous digital cash may well be less that for identified digital money systems. [reasons elided]
Digital cash, on the other hand, needs a redeemed note database, but this is one of its only unique costs. [snip] It is likely that digital cash is more efficient economically, since it unbundles a bunch of previously linked services and allows them to be purchased separately by those who actually need them.
Halleluja! Eric, for the last three months, you have said that there was no way to prove whether digital cash was more cost effective than other forms of e$, and thus potential efficiency was useless as an economic argument for its adoption. Perry and have held that it must be, and you have just now given a bunch of real good reasons. Now we need to figure how to test all this out... I love this place...

If there were already a fully identified digital money system,
Is there one? I don't think there is any digital money system at all, neither anonymous nor fuly identified. There certainly are digital funds transfer systems, almost all fully identified. These are not digital money systems, although they may be precursors. Eric, for the last three months, you have said that there was no way to prove whether digital cash was more cost effective than other forms of e$, and thus potential efficiency was useless as an economic argument for its adoption. I still agree that you cannot really _prove_ that it will be more efficiently, at least not from armchair business planning. Given a few million for a good study though, I'm sure answers might be forthcoming. What is apparent, however, is that it is certainly reasonable to examine the possibility that digital cash might be cheaper to implement. Eric

The U.S. banking system is largely a "digital money system" in the sense that the bulk of the money in the system is represented in book entry form in computer systems and has no other existance. Perry

Well, just to pick nits, I'm referring to a retail-level, digital, general-purpose, bidirectional transaction system. That doesn't exist yet. (Credit cards aren't bidirectional.) Certainly, though, the book entry money that is the world's high end monetary accounting is all digitized at this point. Eric
