Imagine a group of "concerned nation states" collaborate on issuing an international arrest warrant for the Bitcoin devs for "conspiracy to launder money", or "conspiracy to fund terrorist organisations"? How long do you think that would take to draw up, in the event, 6 months?

This ceased to be a computing problem a long time ago, we wouldn't be in this situation if solving computing problems was all we needed to overcome this situation.
