Agreed. Judging by the list of current territorial disputes in Africa (https://en.wikipedia.org/wiki/List_of_territorial_disputes#A...), we're a ways from 'borderless'. Even in the EU, the refugee crisis has made it pretty clear that there are still quite a few borders that people are willing to kill and die over. I agree that improving human mobility and trade can have enormous value, but pretending that doing that is easy (or merely a matter of issuing press releases) does no one any favours.
