I think people like the idea of nationalism, but they have never seen it put into practice properly. Either that or they did and they labeled it as something else (like fascism or whatever). I think it's one of those things were we live in a very complex world and they are trying to apply a simple solution to a complex problem. It just doesn't fit and it never will no matter how long or hard they beat the drum.
I am not sure if nationalism can work effectively in a global world that is interdependent on others. Look at the "egg crisis" around the world due to bird flu - the US is asking Europe for eggs, but there are none to give. Finland could give some (not much due to scale) but the trade barriers are too high. Ironic. This is just eggs. There are many, many more shortages to come as the climate keeps changing.
Yeah - it doesn't fit. It is similar to a barter system being fine for simple trade, but doesn't scale. At some point, tokenization happened - and then was hijacked.
Yeah, that is a good point. My wife was just complaining last night that eggs are $5.50. We have a ton of local sources we could get them from though and we might need to start doing that.
