Wyrre,

You're comparing totally unrelated entities. How does diversity make government better? Diversity in business, technology, genetics is a good thing, but in government??? Come on, think about it. All it does is create nationalism and disparity of wealth. Believe me, I've thought about it a lot.

The only issue that could arise in singularity of government is homogenization of culture. That can be avoided to some extent, however, through physical separation, which occurs anyway naturally. Anyhow, the culture of the world is homogenizing itself as it is. They're building a Disney World in China. I've got a sushi restaurant within walking distance of my house, where I can eat with sticks sitting on the floor. It's entropy of the system of culture. We can deal with it.

Anyhow, please explain (with a real-world example) how diversity of government makes the world better. I don't see any value-adds, only negatives (such as war, poverty, and opression).
