Some parts of ancient greece did have total participation of its citizens in politics. However to support the citizen involvement there was about a five to one ratio of workers who did not have the right to vote. With any sizable habitation some people will have to make decisions and need specific relevent background knowledge (and how to use it appropriatly) so they are unable to carry out the functions (commerce, farming, building etc) that are needed to have the city state operate. If there is a presumption that someone is needed to do this strategic role as almost every political system requires some sort of operator (even anarcho-syndicalism)and your view is that you want to do away with politicians and let the people have greater particapation you are recommending copying classical greek democracy and the ability to operate a democratic society of this model depended on a slave based economy.
