The first civilization arose in Sumer 6,000 years ago. Since then the government has expanded with each expansion of the economy and culture. The next 6,000 years will bring more of the same.
As civilization grows in complexity the government might need to grow to a certain extent, especially since the consequences of failure in a technological society are higher than in an agricultural one. Nuclear power plants, for example. We could go back to being an agricultural society like the Amish but some technology is essential for the enrichment of humanity despite its downsides, like information technology and space travel. Also, the survival of all life on earth depends on humanity being advanced enough to defend it from an eventual cosmic threat like asteroid strikes or solar flares. One possible solution is to have spaces outside of the government where people can practice being good citizens, such as the commons or civil society. Rudolph Steiner argued for a balance between the social, economic and political sectors of society
