I know I will be treated as an extreme futurist, but we live in this little tiny spec called Earth and we're all in this together. The idea that there are laws about environmental protection in one country and none in others, calls to the idea that we should just have a single unifying country called "world" and keep the current separation only for cultural reasons.
The EU was a step in this direction but it seems that yet again centralization of power ended up making things worst. So from one end I'm happy that Greece gets to go its own way and escape centralization that forced it into a shitty situation. On the other hand though, this breaks the dream I had of building a system which would allow better collaboration between nations, and most of all, better understanding of the real issues that we're facing as a species (overpopulation, climate change, food scarcity, etc..).
I've sometimes thought there should be exactly two levels of government... International (non-optional and all countries participate) and County (~2500 km2 and several thousand to maybe 10 million max people).
The world has gotten smaller and the effects nations have on each other larger. It's dangerous and it's not efficient. At the same time people have their local customs and laws (and spending habits). So let that be. But enforce bans on slavery, genocide, trade route monopolization, nuclear weapons, pollution etc. At an international level.
As it is, it seems national governments are in general problematic... both to local communities and to the global community. I think eventually they can be done without.
Personally I prefer the current situation, where a few countries provide a very good standard of living compared to most of the rest of the world, compared to what some parts of the population have to endure even in countries like the US. Globalization does only benefit the very rich in the short term, whereas strong nation states at least to some degree are able to stand up against large multinational coorporations.
