Any massive object existing in a medium (i.e. not a vacuum) if it moves at all by virtue of entering space occupied partially by particles of the medium. Does the purpose of sleep include continuing to exist and not halting movement on a molecular level? Sure, I think if I went to sleep and stopped existing, I failed to sleep. If I froze on a molecular level, I would just be dead and therefore also have failed to sleep.

It's interesting how seamlessly you moved to an un-authored system from the technological and political context this was initially about. You're missing the forest for the trees here, in any case. The real point of the statement is that when you aren't talking about something trivial like molecular-level noise, but the massive and systemically enforced prison slavery system in the US (you know, just to pick an example), it is absurd to say that the production and maintenance of such conditions is somehow contrary to the purpose of the US Justice System, or just some sad incident of fate rather than a lifelong cornerstone of the US economic-political system.
