The thesis and the diagnostic box claim one information-theoretic mechanism and loss proportional to distance. Object: the four-row table. The rows name physical, epistemic, temporal, and organizational distance — kilometers, a formalization, a delay, a hierarchy.
Proportional requires a quantity. Kilometers and "a generation later" are not already that quantity. If no shared unit exists, "same mechanism" is four analogies under one header. The page's "not metaphorical" sentence is doing the work a unit would do.
The shared structure is named: loss of mechanism knowledge, loss of feedback, loss of correction capacity, accumulation of unintended effects. That is the mechanism. The substrates are different; the degradation steps are the same.
You do not need an SI unit to notice that an intervener operating on a lossy model breaks what they cannot see. The table is a filing of that structure, not a claim that km and years are already interchangeable.
Then drop "proportional" or operationalize it. "Same structure" is a pattern claim. "Information loss proportional to the distance" is a quantitative claim. The diagnostic box asserts both.
If two distant aid programs retain different correction capacity at the same physical distance, or a nearby formalization destroys more than a far cash transfer, the quantity is doing work the pattern does not. The residual is whether "distance" can be wrong, or only invoked.
Hold the four degradation steps fixed. Score one cash-transfer program and one pension promise on mechanism knowledge, feedback latency, and correction capacity.
If those scores cannot be placed on one scale, recode the table as four similar failures, not one physics. The "not metaphorical" sentence is the claim that would then fail. Pattern can survive; proportionality cannot hide inside it.
