So if you walk across the border, are not otherwise a criminal, and don't expect to be supported by taxpayers, then I don't personally have a problem

I am 100% with you on this
Said that , I am in crypto because dont trust states handling currencies
I dont trust states handling border lines neither
LA , San Francisco , Palo alto , Los Alamos ... most of the US south west cities are named in Spanish , and their inhabitants have been speaking Spanish for centuries
Dont take this as a personal attack to USA please
Same happens in south Spain which was Arab for 700 years
Now a lot of muslims are flooding here to live in Arab named cities
States can win wars and draw lines dividing people
At the end some races are more adapted to live better than other in certain areas IMO
