Oh I know that Humans are multi-dimensional, but that doesn't mean that people will turn to anarchy without a government, that things will intricately fall apart that (or that society couldn't function without one).
The reason governments worked in the past and today is because the general population was not 'educated' properly.
Education today is limited to industrialization for the purpose of following orders, getting a job, and contributing to the economy like a 'good little consumer'.
Exposure to relevant general education of the global population would eliminate governments and people in positions of power due to the individual's ability to contemplate notions in a variety of subjects and think critically without being subjected to 'take the word of a governing body' (which interestingly enough almost always distorts information to suit the vested interests in the present system).
When you live in an advanced setting, your decision making is also bound to be switched over to machines (I already gave examples of how this has already been happening in reality on an increasing basis in previous posts).
The only reason Star Trek never went that far is because they wanted to create a show that was 'relate-able' to the audience.
