It’s clear that this assumption may be refined in two ways: accounting for spherical geometry and accounting for agriculture conditions, both of which will result in higher density near equator and thus larger Earth radius in this calculation. But if we are interesting to estimate Earth’s radius just up to order of magnitude, it will still work.
The main idea was to present another DA-style calculation and check if DA-logic works. It works.
Before accounting for agricultural conditions you probably should account for the distribution of land masses… But anyway, how is this a “DA-style calculation”?
DA-style here means that my position is some set is used to estimate total size of the set, assuming that I random observer from this set.
DA-style is also means that we ignore other available information about me, Earth etc, but use only my position in the set to get very rough estimate of total size of the set.
The study of such DA-style predictions in known domains could help us estimate validity of DA in unknown domains.

Isn’t this approach better known as “generalising from one example”?
No, it is evidence, but very vague.
