I also understood something very similar to what you said.

That building alternatives outside of capitalism on is no longer an option for broader political change because we are running out of time due to the ecological crisis. In the same time, it's through that kind of practices, but reframed, that we can expect the necessary solidarity for survival to be created.

slowly building alternative modes of living in the cracks left by capitalism. Then, when an existential crisis comes together with a powerful movement, we might topple capitalism and live in those expanded interstitial spaces. That was all well and good as long as we had infinite time.

These spaces [workers’ cooperatives, commons projects, eco-villages] are still what it’s about. Temporary Autonomous Zones. It was very popular in the 90s. That’s still what we’re talking about. I’m just not assuming they’ll come together like an archipelago that grows into a continent and displaces capitalism. I’m imagining, at best, an archipelago of solidaristic spaces you can hop between without your foot touching fascist ground. Spaces where life can still be lived the way it should be lived, in solidarity and freely. It’s the same strategy, but with a different goal. That requires adjusting our expectations to the new reality.

Yes and no. Of course it is about building leftist (infra)structures that could be used in case of system failure in the age of collapse. But because you can not build everything anew in parallel completely separate, it is about augmentation and cooperation with (state) institutions and NGOs as well.
