Scale is half the problem. There is a reason that climate destruction, world-spanning wars, nuclear weapons, etc. all took off the same time that population exploded. You can't separate scale from technology from destruction. I'm not arguing for de-dev, but the complex, "scalable" systems we've built and now rely on are literally either designed to kill us or are inadvertently killing us (emission, plastics, deforestation, PFAS, etc.

I'm not sure where you got the idea that I'm advocating being unprepared for evil? Even in Anarchist systems, which do not have systems of authority, the use of force to counter someone hurting you is well understood.

If your argument is that state systems will scale large enough to destroy non-state systems, I agree, but then you're just agreeing with what I said about the state setting itself up as a threat that must be participated with in order to counter (i.e. in this case arguing, "if you don't want the state to consume you, make your own state"). That doesn't make those other systems bad, it makes states bad. "Might makes right" is not generally considered a very modern or positive way of interacting with each other.
