Justice requires borders. Without borders, there is no incentive for a people to work and fight and give their lives to build a way of life for themselves and to establish order and to allocate property rights among themselves. Without borders, people who fail to establish a functioning society have no incentive to fix the problem; instead, they just leave it and invade the territory of a people who have succeeded in creating a well functioning system. Without borders, everywhere becomes frontier, and humanity finds itself on a worldwide battlefield, on a frontier where various factions compete to seize territory. Without borders, race becomes the border and the color of one's skin becomes the flag of your allegiance.
The idea that humanity would be better without borders is equivalent to the idea that we would be better off abolishing, and rebuilding from scratch, all of the order that so many people lived and died to create so that we would be able to enjoy an "ordered liberty".
The idea that humanity would be better off without borders has got to be the STUPIDEST idea that I've seen yet on steemit.
What Carlos Santana is really talking about is justice. Justice for Mexicans and for North Koreans and for Chinese and for other peoples who are trapped within the boundaries of FAILED SYSTEMS will not come from abolishing borders. It will come from people operating from SUCCESSFUL SYSTEMS like the United States of America to use the Internet to empower individuals worldwide so that they can overthrow their opporessor governments and clean their own house.
