What is the Role of the State?

When I teach the History of Economic Thought, one thing we focus on is how views on the role of the state have changed over time. It has a natural cycle to it, with eras such as the highly interventionist Mercantilist years followed by Physiocratic and Classical views stressing minimal government intervention. This is followed by a rebound in the other direction, and so it goes with a Keynes followed by a Friedman in the 50s, a rebound back to Keynes in the 60s, to classical ideas following the experience of the 70s, and so on, and so on. We are involved in the same debate, and a smaller version of the grand historical lurches in each direction, yet again today:
What is the role of the state?, by Martin Wolf: It is … a good time to ask … the biggest question in political economy: what is the role of the state? This question has concerned western thinkers at least since Plato (5th-4th century BCE). It has also concerned thinkers in other cultural traditions… The perspective here is that of the contemporary democratic west.
The core purpose of the state is protection. This view would be shared by everybody, except anarchists… Contemporary Somalia shows the horrors that can befall a stateless society. Yet horrors can also befall a society with an over-mighty state. …
Mancur Olson argued that the state was a “stationary bandit”. A stationary bandit is better than a “roving bandit”, because the latter has no interest in developing the economy, while the former does. But it may not be much better, because those who control the state will seek to extract the surplus over subsistence generated by those under their control.
In the contemporary west, there are three protections against undue exploitation by the stationary bandit: exit, voice … and restraint. By “exit”, I mean the possibility of escaping from the control of a given jurisdiction, by emigration, capital flight or some form of market exchange. By “voice”, I mean a degree of control over, the state, most obviously by voting. By “restraint”, I mean independent courts, division of powers, federalism and entrenched rights.
This, then, is a brief background to … the problem, which is defining what a democratic state … is entitled to
