Another important issue related to border is regional spillover or externality. Border areas might have to bear positive or negative spillover effects from neighboring regions. One example is that some scholar (Zhou, Li-An) found in China that a county with more borders tends to be less developed. That finding is interpreted as evidence for zero-sum competition among provinces, which do not want to invest in bordering counties so that neighboring province might benefit from spillover effects of the potential investment.

They are important to reinforce the discourse against the necropolitics and necropower of the global north over the global south and the need to tear down the fortifications built around the European Union and the United States.
You need historical dimensions to approach this question. "Nations" are young and deeply problematic constructs. With language (standing for ethnic or, even worse, racial, "sameness) and/or reiigion as the logic for territorial borders, there was "emotion" there to begin with. If you go back in time, you had empires with a perhaps more economic logic undergirding the power game fuelling expansion and thus shifting borders. if you come closer to the present, you have colonial powers drawing absurdly straight borders for new states they left behind for a postcolonial era, in their ignorance often cutting right through tribal territories. Emotion is thus hardly the issue to foreground but rather power and ignorance.
