Meta: i like this question, there are interesting undertones here.
As for Kaczynski, i like some of his writings, but i think we should consign him to join the rest of the old-men-with-grey-beards; his thoughts are as much conditioned by his time as those of Bakunin and Proudhon.
If i recall correctly, in the beginning was the Church, the State, and the Capital. In industrialized countries, the church has been downgraded, with Science covering the widening gaps between its butt-flaps, while Capital pretends to ascend to unquestioned piety. But as ever, the State reserves its monopoly of violence; violence to guarantee the property of Capital, violence to guarantee the priveleges of the Churchs, violence within and without.
(In his 'System', Kacz. aggregates State, Capital, Science; whether he meant what we condemn as 'Civilization', or whether a specific fraction of it, is unclear to me. I will say that i reject the idea of any person in a position of influence being in conflict with the 'system'; any person in a position of influence will either support the 'system', or they will be culled, cast out, excommunicated, etc..., they are all disposable. )
