On the other-hand, you can also envision an anarchist future much like Gibson's novells where everyone is a free agent and thus out for his own good: capitalism.
It is only through theory that an pseudoanarchist capitalist State can exist, read Ayn Rand's _Atlas Shrugged_ and you'll see my point. Gibson's futuristic view is not anarchy, it is multi-national oligarchy to an extreme. If you have read all his novels (I assume you have) you'll notice that he mentions how the economy, and the resulting power from that pure free-market economy, is of a corporate nature, and that power lies not in the members of the board, but of the zaibatsus in themselves; that they behave as organic beings. His vision is far from anarchy, and his version of free-market libertarian economics should never be confused with the apolitical (antibehavior-control) aspects of anarchy. [also, I think that he isn't trying to make political or economic statements with his books, but that those details enhance the effect of his stories (just my opinion)] All this talk about one particular form of digicash has me wondering: why not multiple forms of digicurrency? This would decentralize any kind of power electronic banks would have through monetary strength, and ensure that those banks do not add themselves to the system as inconspicuous political parties (anarchy is the end, and reducing, not creating, political power is the means, right?).
