It's a real shame that just when we have the tech and infrastructure to allow people to travel anywhere in the world within a day, for a single person to be able to explore the entirety of this awesome planet for the first time in human history,
that the worst among us have to enforce artificial borders and deny everyone this basic freedom.
Travel should be codified as a human right.
If someone can support themselves and doesn't harm anybody, what ethical justification does anybody have for denying a person from living where they want?
