I basically agree with all of this. The question we then urgently need to answer is how does this kind of left reproduce itself? If all you are is a protest movement you can survive on donations of time and money. But to build load-bearing collapse infrastructure demands far more resources. https://climatejustice.social/@muellertadzio/112540033144186576
The fascists have a simple route to reproducing their movement. They skim off money from angry privileged people to start with and eventually take control of parts of the state, plus make alliances with business.
Neither of these models fits with the mission of a collapse left. Partly because we need to reject depending on the state, but especially because the catastrophic movement involves the collapse of the state, the transformation of the state and the atrophy of the 'ethical state'.
The only model of reproduction that I can see as viable is the syndicalist model and the liberation model. In the first, the movement is based on demanding resources from employers through explicit or tacit bargains. In the second we liberate our own resources currently lost to the daily grind.
