I agree. I was just trying to come up with different terminology for IOU in ripple, but gave up, because that's exactly what it is. We don't deposit money in banks, we lend our money to the bank.
Same with MtGox. We deposit fiat, and we get IOUs which are a database entry in their MySQL server. Then you buy Bitcoins on the exchange but you are really getting Bitcoin IOUs which also sit in their database. When you withdraw US Dollars from MtGox you get IOUs from your bank instead of MtGox IOUs. It is only when you withdraw Bitcoins to a wallet under your control that you actually have something which is not debt based and without counterparty risk.
What Ripple nay-sayers don't realize is that Ripple functions identically to the MtGox scenario, it's just more explicit. It would be like being able to send your "MtGox US Dollar IOUs" in a cryptographically secure way to anyone else with a Ripple wallet. Clearly, this is useful and not a "scam" as forum trolls would have us think.
No. I am a ripple nay-sayer and I do that exactly because I realize ripple functions like MtGox and to say it even more extreme, it operates exactly like banks.
I hate banks and I hate MtGox. Unfortunately I have to use banks and I have to use MtGox, but the less I use them the better and the less time I have my money on them is better. Hopefully in the future I can be able to use them even less and if I happen to develop a particular distaste for some of them I would like to retain my capability to completely cut my ties to any of them. I am not going to root for Citibank, Bank of America, MtGox or Ripple.
Actually ripple can be said to actually be even more fundamentally evil than regular banks. When people say banks can print money out from nothing that is true only in figurative way, not literally. Ripple on the other hand actually and literally prints their own money. There is no way I can support that. Ripple is totally 100% opposite to bitcoin in what it will do to the world monetary system if it ever happens to take over. Much more dangerous than normal banks and there is actually nothing that can neutralize that threat. No matter how much opensourcing, no matter how much forking or no amount of dubious decentralization within ripple will change that fundamental. Those acts just multiply the evil. They do not eliminate it.
I find it funny that some lipservice to bitcoin ideals is enough to convince many bitcoin advocates to completely turn around to support ripple.
