I think I can agree with your basic premise, as human beings we have a fundamental, basic even inalienable right to any part of our planet. The fact is humans living in a particular generation are far more connected to each other than to our ancestors. The problem is this is classic utopianism completely divorced from the historical development of our political and economic systems, property rights and the structure of nation states and societies. Tribalism will always perpetuate the concept of the outsider and a natural suspicion, and often with good reason. That's how colonialism happened. In any time going and being accepted in other societies is 2 different things. In other times we would need technology and resources to travel, account for disease and the reception of native populations. Now we have nation states and rule of law that governs movement of people for travel and emigration. These rules can be improved but there is no alternative that does not impose controls, even if we have post nation states there will still be controls. What I would like is significantly less restrictions and more 'openness' and good faith policies that acknowleged every human being's right to travel and see the rest of 'their world' unhindered.
