You know, thinking about it, I think Jack is the first crazy person I have seriously dealt with at length on the Internet. Oh, I've seen plenty of crazy people online - I've laughed at Timecube, I've looked over HN's own resident Losethos (with a sense of 'there but for the grace of god'), I've watched other people argue with crazy people - but I think I've either never actually dealt with them or quickly flipped the bozo bit on them and disengaged. Under normal situations, on normal topics, I have no reason to talk with them at length and grandiloquence is unjustified....
At least part of the problem here is that in the crazy mirror land of the blackmarkets and Bitcoin in general, sanity is hard to distinguish from insanity, there really are key bits of information random parties can have, not everyone talks straight, blackmail does payoff, and there really are hidden millionaires & billionaires walking around in plain sight. (As an example of the mirrors of insanity, I invite anyone to read the Silk Road 2 forums and parse the SSBD/Inigo/Libertas, the DPR2 key rotation, the Cirrus announcement, Raoul's quoted message from DPR2, the posts by Defcon, the 'accidental' access to the admin forum, Ormsby's comments, Oracle's insinuations, the Tormarket quote from the vendor forum, etc etc etc, and parse it into a single coherent sane narrative. And consider what Satoshi's estimated fortune is at any moment.)
