When we assume Digital Mechanism, we are duplicable, and in that setting, a 
good first approximation of the difference between 3p and 1p is the content of 
the diary that the candidate (for duplication) take with him in the 
cut-read-copy box. I don’t see the non-sense you allude too. It helps the 
intuition about the fact that a machine cannot know which computations (in 
arithmetic or any model of a first order Turing-complete theory) is running 
him/her.
