I think you're a bit behind on the debate, friend.
It seems to me we've pretty much come to a consensus that centralization of certain bitcoin functions is inevitable, and even desirable.
The whole anarcho-libertarian cryptastic orgycoin concept is only appealing for a very select minority.
So, it's very very likely that demand could dry up quite quickly unless such centralization takes hold.
I don't understand how any of you got the idea in your heads that decentralized currency was ever in demand...frankly, the entire world minus you an d a couple of your buddies we could write down in a small notepad, simply do not give two flying fucks about crapto-currency.
You haven't dealt with a lot of small business owners, have you? The concept of a low-cost means of exchange that doesn't have a single authority that can arbitrarily reverse a transaction six months after a sale is extremely appealing.
You haven't dealt with a lot of consumers, have you? The concept of an insured, high security means of exchange that doesn't have many disconnected and possibly untrustworthy entities, that can also allow you to dispute a charge when the product or service delivered is unsatisfactory, without having to resort to bringing a lawsuit, is extremely appealing...
And then?
