Concentración de Poder

Hay un sitio que suele tener comentarios muy interesantes sobre cuestiones económicas, se llama The Angry Economist. Esta vez el Angry Economist incluye un post para pensar: se puede decir que toda concentración de poder es mala, por lo tanto los monopolios son malos. Sin embargo, aceptamos como algo natural el monopolio del estado:

Trying to overwhelm the concentrated power of a corporation by concentrating power in government is wrong. When a large company misuses its power, your action should be to make it smaller by buying from its competition. Even monopolies (e.g. Microsoft) have competition (e.g. Macintosh and Linux). I happen to believe that no government function is necessary, but I recognize that that is not a mainstream view. Most people support the idea of governments. How do you get away from having a monopoly government, though? How can you have competitive governments?
