Paper mills and later industrial paper scale energy-and-resource use behind cheap print
As presses multiplied after Mainz, paper-mill production had to scale, using water-power and rag supply. In the causal graph this event weakens Energy Security, a driver that strengthens Poverty headcount ratio at $3.00 a day (2021 PPP) (% of population) — an improving welfare path.

As presses multiplied after Mainz, paper-mill production had to scale, using water-power and rag supply.
Context
The driver is analogical for a fifteenth-century mill. Confidence medium. Still a real input: no paper, no 42-line Bible at volume.
Johannes Gutenberg is not the sole author of every later object, law, or museum label that uses the name. Shared work with courts, excavators, printers, spouses, officials, and later states does not erase a documented role, and it does not make an ancient person the signer of a twentieth-century statute.
Why it matters
Resource-input path. Medium confidence.
A mill-wheel is not a Bible. Keep the book as access and the mill as input.
Who was responsible
Contribution type and responsibility level for each recorded actor — not sole-author shorthand.

Complex: millers and later industrial paper. His product-line increased paper demand.

What the sources establish
Print-history essays on paper supply and academic mill history independently link presses to paper demand.
Established: expanding print required expanding paper-mill output. Not established: a kWh series for 1480, or Gutenberg as a miller.
