The only thing is, if you have a bank beyond anyone's regulation or control like that...
...what happens if you get a bad apple in there? A Ken Lay?
Just imagine the destruction the collapse of that could cause, as someone bailed out with their extorted golden parachute and vanished…
I would argue that the Ken Lay's, and things like the Savings & Loan scandal of the 80's happened under the government's watch. It's also arguable that government regulation and oversight is what creates the loopholes that allows some of these things to happen. I think the free market can do no worse, and with no FDIC "safety net" to make people sloppy, and the e-bank offering the highest security and privacy getting all the customers in a pure market solution, it's possible you might get a bank that's fraud-proof.
There's ways to set such a bank up that makes raiding it unlikely. Such a baink might even be "open source" after a fashion, where all the users can monitor the bank's activity in such a way that the banks operations are transparent to all it's users, but privacy is maintained. You'd have millions of hackers, governments, drug dealers, math/economic/game-theroy professors, the mob, and cranky libertarians all looking over their shoulder.
I'd rather try and decieve the IRS or the FDIC, then the massed forces of the entire Internet any day of the week.
Just look how they all jump down Microsoft's throat when they find a security bug, and that's just for their own personal gratification… If it was their money on the line? Holy… better watch out...
And as I alluded to in my earlier post, such an "e-bank" that uses mathematical mony based on un-forgable encryption, it would be impossible for your money to be "taken" unless you give the encryption key, even by the "banker" himself. And if there is a crack in the encryption, someone with enough computing power to steal your funds (we're talking more computing power on earth, perhaps the universe, with tough enough encryption.) Would be so rich (and nearly God-like over so many other aspects of our lives), why bother ripping you off?
If it's set up right, the worst a corrupt banker could do is destroy the bank, but he would lose all his money like everyone else. And if it's a distributed system with no central point of control, just like the Internet, or the peer-to-peer music sharing networks, there's no way to dominate the bank without destroying the entire net. It could even be set up like those distributed computing projects like the cancer thing, or SETI@home where instead. millions of members around the world keep a tiny chunks of "the bank" on their home PC's with massive redundancy around the globe.
The "money" would be kind of like PGP, where there's a public key, and a private key. The public keyblock is out there for everyone to see, but it's still encrypted, and can be used by anyone to send you a private message that only you can unlock. Your money would be the same way. You pay someone, or they pay you, and it's encrypted with the public key, and the private key unlocks the money to accept it. All the bank knows is that some person or business with a key encrypted X amount of money, and sent it to someone who could unlock it. They have no idea who they are, where they are, or what it was for, nor do they care, in fact, they actively don't want to know...
Such a system, if it it was widely accepted (and this is the A-1 BIG "IF" just like any money or banking system that's come before it), may well be unstoppable, to the point governemtnts will have to capitulate as their reserve banks become iirelevant, and their ability to tax dissapears. If enough people and businesses adopt such a system faster than governments can crack down on it, it would reach an unstoppable critical mass. You then may see a period in human history where no one is forced to pay for something they don't want ever again.
Such a monetary system would be more revolutionary than the Internet itself.
