Forgetting for a moment all of the technical, physical, ethical, and philosophical issues associated with teleportation, it seems clear that if we ever invented an instant transport device, all hope of security would be out the window. Not just because people would be moving around, but we could ship anything we wanted anywhere across any borders in a manner that seems completely impossible to regulate (let alone tax or audit).

Maybe the devolution of humanity back into chaos will not come at the hands of nuclear weapons after all, but instead under the shining innovative umbrella of teleportation?
