Will all e-commerce be socialised - what about transaction costs?

Update - StoweBoyd has commented on this post that Esther Dyson made, (we commented on our view that she was possibly in error re Dopplr over here, mainly because the functions she ascribes to closed systems like Dopplr will be done "in the wild" soon) but he makes an interesting point:

I wrote years ago that in the future, all e-commerce would be socialized. Looks like we are about to pass over that horizon.

Its an interesting idea, but we were debating this at a recent VRM meeting, and I've now come away with the realisation that not all e-commerce will be socialised per se - there is going to be a subsection where either the value of the transaction, or the transaction cost of providing it, will make a pure price based transaction necessary.

In essence a pure price finding transaction takes away the need to socialise (which has its own frictions and costs) as it is a very simple, low cost transaction, and in some environments it will be the most efficient, or the only transaction cost that market will bear.
