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.
