The author literally gloats that Ulbricht will never live outside a concrete box, as due punishment ("he had been held accountable") for the sole "sin" (his word, not mine) of creating a drug marketplace.

There is no mention that the internet hitmen saga is a predictable and avoidable negative effect of prohibition (having to resolve disputes by extrajudicial violence instead of having access to lawyers/courts/arbitration), there's no mention that none of the murders-for-hire had actually been done (every internet hitman is a fed and/or scammer) and he, AFAICT, hasn't even been convicted of the procuring murder charges.
