The title is a bit ambiguous. Also, the "May" is weasely on my part. But I think you raise a fair point. It is unclear how insurrection really fits into this Disaster Anarchism.

I understood the attached article to mean that we have to focus on continuously building up our disaster response, and that will help us to continue functioning if we are cut off, partially or fully, from the dominant system. Insurrection would likely cut us off significantly from the dominant system.

What is not clear to me is that Disaster Anarchism tells us to try to avoid focusing on insurrection as a means of change, but it does not tell us what is a good time for an insurrection. And I think that is where your point comes in.

Personally, I think it makes more sense to think of Disaster Anarchism as occurring in parallel to, not instead of, insurrection.
