Ranchers add ladders to border fencesRanchers could build walls, of course. There could be a series of walls, each circumscribing a state-like entity (although tax-free zone) for which ladders function as visas. Immigrants could move into the US little by little, according to the system of scalable visas, working in one mini-state and then another once the ladder-visa rules change based on labor demand. They could open restaurants and an informal social services sector, restrained only by how efficiently ladder transport of goods functions.
A few Texas ranchers tired of costly repairs to cattle fences damaged by illegal immigrants have installed an easier route over the U.S.-Mexican border — ladders...
If ladder-visas are amended or denied while the immigrant resides within the mini-state, we could have a de facto system of indentured servitude in which immigrants pay into a ladder-purchasing system if they choose to move into a different mini-state. Immigrants would not know the conditions in the next mini-state, however, and their risk-assessment of the process of ladder-purchasing, and installation would thus have a naturally conservative element. Risk assessment would be conditioned by high levels of uncertainty.
Said constructive ladder-visas would be based on fluctuating demands for cheap labor and resource-use within each mini-state. The economy of mini-states could thereby function as voluntary immigrant credit-trading. Why not draw up a picture ID system and trade them like baseball cards between mini-states? The mini-state economies might, however, also be based on a system of voluntary controls installed by immigrants in which their own ladder-purchasing regulates and distributes the flow of ladder transport of goods, services, and labor. If needed, they might even create well-regulated militias to enforce such regulation and distribution.
We shall call this system - or civitas - of mini-states the Cellular State, comprised as it is of individual cells which themselves constitute the Body Politick of the Unity of States.
