I fear this might be dire to the Bitcoin economy. Skirting wealth flight laws WAS Bitcoin's killer feature. All of the other Bitcoin use cases I know of are incremental in nature (ie, 2.5% savings on e-commerce transactions).
The open question is if enough of a hype-market was built to keep the other use cases alive. In the case of e-commerce, I assume a rational merchant only accepted Bitcoin because of 1) viral marketing channel 2) speculative hoarding.
The speculation MIGHT work out if the underlying Bitcoin economy was powered by the transaction volume and value of international wealth movement. Running forward it'll be from e-commerce and store of wealth, and I'm skeptical if that'll be enough.
