Pro-E.7 --- Response to Con-E.7 (Composition Fallacy)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
*Impact: E (Moderate) --- Resolved.*

The composition fallacy charge is incorrect because **civilization is
not a portfolio of independent innovations** but a single tightly
coupled system with shared infrastructure: energy grids, financial
systems, supply chains, communication networks, ecosystem services.

**Key evidence of tight coupling:**

- **2008 financial crisis:** Failure in one sector (subprime mortgages)
  propagated through the global financial system via interconnection.

- **Climate change:** Violation of Life-friendly in energy innovation
  propagates to agriculture, water supply, migration, and political
  stability.

- **Nuclear proliferation:** A single innovation (atomic weapons) that
  violates Life-friendly creates an extinction-level threat for the
  entire civilization.

**Academic support:** Helbing (2013), *Nature* 497:51–59, documents
how global interconnection creates systemic risks where local failures
cascade into global crises. Buldyrev et al. (2010), *Nature*
464:1025–1028, formally demonstrate that interdependent networks are
more fragile than independent ones: failure in one network triggers
failures in coupled networks.

**Why Impact E, not higher:** The coupling argument is compelling but
the coupling strength is asserted from examples, not formally
quantified. The argument would be stronger with a formal model of
civilizational coupling.
