Boiled down to its essentials, this argument can be expressed by the lyrics of the song "Bad Boys" as used as the theme song of the reality TV show "Cops." For those who no longer participate in the previous culture, they are:
Bad Boys, Bad Boys Whatcha gonna do? Whatcha gonna do when they come for you? Bad Boys, Bad Boys
repeat endlessly.
I would suggest instead that the critics of cryptoanarchy are out of touch with "physical reality."
For the "Bad Boys" to come for you, a whole series of requirements must be in place:
1) There must be Bad Boys 2) They must be able to travel 3) There must be a reason for them to come "for you". They need motivation 4) There must be a you 5) The Bad Boys must know where you are 6) The Bad Boys must be able to travel to where you are 7) The answer to the question "Whatcha gonna do?" must be "nothing" (This would seem to be implied by the song.) 8) They must have something to do to you when they "come for you" otherwise the journey is a waste of time.
I dislike having to follow up something so unrelated, but the bad boys are the criminals, the song is about what will you do when the cops come for you. The cops are not the "bad boys" in the song. Trust me. Mark
