I mean, in his defense, it sure seems like, in order to procure any novel insights about something as strange as capitalism, one is almost required to go off the deep end, right? That is, unless you take a more empirical or economic approach.
Not quite sure it necessitates dealings with esoterica and the occult, but such a combo can potentially yield insights, no? I'm certainly not inclined to reject such matters (lemurs, numogram, etc) wholesale, but I can also see where such things can enamor people purely by virtue of their mystique. Doesn't seem to be the case with Land, though. His point about the means of production seeking to gain autonomy is, as far as I can tell, a novel thesis. Perhaps there were seeds in D&G, or perhaps they even explicitly argued it, in which case I'm not sure what Land brings to the table. Also, I'm far from being an expert on the guy - there could very well be clear right-wing stuff in his thought. I'm just going off of what I know.
I'm inclined to believe many of us here have heard enough from Land and any apologists of him, but there seems to be a robust loss if we just cast him aside as some right-wing burnout lunatic. It seems like he just became "right wing" because he became convinced that a proper/traditional opposition to capitalism was not only fruitless, but even counter-productive. I don't see that as a space exclusively reserved for right wing thought. It could be, but I'm far from convinced. And I can hardly blame the guy for going insane, we all know its head-splitting stuff.
And meta-nomad (Hermitix host, don't know his name) seems to be very influenced by Land. He was leading a reading group for Thirst for Annihilation.
And I get the strange and uneasy suspicion of crypto-right-wing ideology underpinning some of these currents, but I don't think such underpinnings are essential to much of this thought. But I also am suspicious of that suspicion. Again, I could be way off base.
If my defense of him seems strange and protracted, its because I think he represents something much larger. He seems to represent, perhaps better than anyone else I can call to mind (maybe D&G), what happens when you carry/push the left-wing impetus to its extreme, or at least one of its extremes. To ignore that, I think, could be fatal, or at least unwise.
