I take a very literal approach to "the state." The state is the status quo. The way things currently are. The totality of social relations. The state is what keeps Haskell programmers awake at night. Nothing more, nothing less.

A hippie commune, an Anarchist book club, a Syndicalist federation, and a dictatorship of the proletariat helmed by a Communist party are all states. It isn't very useful to argue about what is and isn't a state. It is much more interesting to explore how these various forms of social organization differ in composition and outcome. To learn from effective practice, incorporate the triumphs of past movements, while avoiding the mistakes. Differing conditions call for differing tactics, and it doesn't behoove anybody to be too dogmatic.
