One of the problems is that masses are used to, 'trained' to be managed in groups (teams, factions, states, nations...).
Having no Politicians or no Government would require the masses to be much better human beings with a much higher sense of discipline, right/wrong. Masses will feel lost without group heads.
A new generation would need to be educated differently, from birth, to be able to understand how to live without politicians.
Education is a huge factor. We are not trained to solve the world's problems or live in a humanitarian and forward-moving fashion. We're only trained to respond to the needs of management.
