The Fuller Projection is by design borderless, but that doesn't change the situation on the ground one iotum i.e. we don't have borders as geographical features of Planet Earth, but we may have walls that define where these borders would be i.e. walls that follow the property lines. We have different words for property lines and borders in that the latter are more a subset of the former. "Walls" are a stand-in for barriers of various types.
The point of showing the bare stage, minus the marks and lines necessary to the current plays and dramas, is to remind ourselves that we live through theater. We express ourselves through our characters, which are in turn defined in terms of attributes, such as citizenship in one or more nations, or refugee status. We need to keep all that political data front and center, or risk changing our character.
Could someone join a roster of citizens minus moving to that very territory? What if there is no such territory, only a smattering of facilities around the world? Yet this network offers citizenship? Could a golf club offer citizenship as another form of lifetime membership? If not a golf club, then a virtual nation?
Instead of knowing the answers to such questions, I toss them out there to help shape the conversation about what's in need of ongoing design. These concepts were passed down through many generations. What did it mean to be a citizen of Rome? Of Athens? How has the concept of citizenship evolved?
Using television to show us exactly what is going on in various borderlands, in terms of barriers, defenses, drug dealing, would be elucidating and feed the computation. Is the Canadian border somehow less permeable to fentanyl? How might the medical profession take over the drugs problem from those into crime and punishment? Does the wall in Judea-Mesopotamia define the borders of a nation state? Define "nation state".
Again, I'm not the answer man. I just know the humans alive today have responsibilities to keep working out their differences.
