Be careful what you argue for.
For the longest time I was opposing nationalism and the concept of citizenship. I researched the issue, read and crafted arguments in favour of my position and convinced myself that this is a rational opinion to have. Then some things happened that made me feel more connected to the soil I was born on. Still I feel that my identity is not determined by my passport but my previous arguments seem a whole lot less convincing and the arguments I dismissed as unreasonable seem more convincing.
The quest to be more rational is one of the more humbling things I ever did with the hardest lesson to learn being that I am wrong very often and my beliefs are largely not rational.
I think your thought process is indicative of our modern age. It is hard to concept of nations in the online environment that, at least for the time being, remains borderless. Nationalism has produced 2 world wars and several smaller conflicts and given its impetus in 1648 as a way of allowing kingdoms and countries to decide their religion without outside influence I think the 21st century will see fewer borders rather than more borders. That being said a quick read of any news site would make that statement hard to believe as nations get more nationalist...
