The court enters its strangest case of the term: two of humanity's oldest inventions, in single combat. No appeals.
RED CORNER
Doors gatekeep civilization
Every wall is just a wall until you put a door in it. Doors invented privacy, security, hospitality, and the entire concept of being "inside." A wheel rolls; a door decides who gets to roll where. Civilizations are organized around thresholds, not axles. The door is the unit of control.
BLUE CORNER
Without wheels, no logistics
Without the wheel there is no cart, no gear, no turbine, no car, no industrial revolution, no global supply chain, no civilization at the scale we know it. Doors only matter because wheels move enough stuff into buildings for there to be anything worth locking up. The wheel is the substrate. The door is decoration.
