Not everyone thinks the government here is evil. I genuinely believe there's many individuals who believe they can do/are doing good for people. However the entire system has evolved into a corrupted organism. It's not an evil conspiracy but a
'stand alone complex'.Stand Alone Complex eventually came to represent a phenomenon where unrelated, yet very similar actions of individuals create a seemingly concerted effort.
Many of these government institutions once instituted can never disappear. A cancerous growth that drains it's host. War budgets will only ever get larger.
Still, even as I contest the idea that anarchy is sustainable, I can accept that it is possible; and perhaps one day technologies that we can't even imagine today will make a stable anarchy a reality. That could only come if technologies make the primary functions of governments obsolete. But as we have all witnessed over the past 20 years, we can't really fathom what may yet be.
People are socially evolving and changing as a species. New attitudes are taking the place of old attitudes. Economies are shifting to non zero-sum game, service oriented. We may see the first people on Mars this century. In a creative economy, one sees neighbours as team mates rather than competitors because the sum of intelligence of the whole > the few. Because a country has more to gain by pooling intelligence with others than by warring it's inhabitants.
Regarding imaginary lines on a map--that I can get behind. Bitcoin and other borderless realities are the way of the future!
Whether one likes it or not. The leaderless future is inevitable. Extrapolate the ongoing trend and it's clear where everything is headed. Technology has helped massively.
