Bakunin used the term in "Statism and Anarchy" (a literal translation from Russian). If the left doesn't talk about statism, I think it is a testimony to either their pragmatism or their shortsightedness. If one sees the state as the wielder of the monopoly on "legitimate" violence, then conceding to its existence makes it rational to expect that such violence will be used in the interest of one's self within the vaguely agreed constraints of moral conventions. Thus the poor can expect the taxing of some real estate as a way to keep housing affordable, while the rich can expect the police to keep the homeless off their property. True anarchists see a compromise in both instances, and a form of short-term progress in the first one.
