You are right. If you ask me I would say that there should be no borders at all and people should roam our beautiful planet freely! Nevertheless, I wouldn't idealise the travel as it is. I have seen people who have traveled a lot and can't see beyond their nose and people that have lived all their lives in a small settlement in the jungle and their minds are open to the universe itself. But I am sure that you'll make the most out of your future travels :)
