Another angle you're all forgetting is that the CFR may take this opportunity to subtly propagandise their preferred direction of development for cryptocurrencies. Who knows what that could be.

But apparently the very unsubtle strategy of beckoning Gavin towards the Dark Side in a pre-publicised meeting is the only thing that's possible.

I do not see how sabotaging bitcoin itself could possibly work, and anyone who believes otherwise is underestimating the intelligence of this class of people who they dislike/fear so much. My opinion is that we will get to see a cryptocurrency-ubiquitous world monetary system, the concept is too powerful to ever be restrained. If you've spent enough time thinking all the consequences through, you should see that.

But what other changes can we expect to accompany such a world? We would be wise to consider the range of possible changes, as it's much more of an imaginitive leap than "Gavin helps kills bitcoin and we'll be stuck in 2014 type-world forever". That's just about the least likely scenario.
