Anyone who thought the Chinese government were going to ignore a mechanism that allowed people to bypass capital controls with impunity was pretty naive.
Bitcoin fanboys have classic tunnel vision - they're so enamoured of the libertarian ideal of an anonymous crypto-currency that's not controlled by any government, that they ignored all the practical, economic and legal challenges it would need to overcome before it could become a real currency.
It's a bit like the people who watched the moon landings on TV and believed that we'd have moonbases by the end of the 20th century. Technology needs time to develop and mature, and there typically needs to be a compelling commercial case for its adoption.
The technological principles that underpin Bitcoin will see more widespread adoption within the next few years but they'll be deployed within the pre-existing financial context, perhaps as a mechanism for OTC trading or to support real-time gross settlement in the wholesale markets. In the retail market, I envisage an M-Pesa-style digital payments/money-transfer solution that complements the the traditional banking and payments systems. We might see alternative currencies built on Bitcoin-style infrastructures but based on something that people value in a different way from dollars and cents (e.g. the rainforest).
But Bitcoin itself is too flawed from an economic perspective, too inefficient and too big a step to be able to function effectively as a currency within the current AML/sanctions-focused regulatory environment.
