Similar to anarchism with a large overlap but I would say it includes other related ideologies as well. To be an anarchist I think you need to be very anti-capitalist and very anti-state. I think left libertarianism needs to be at minimum very skeptical of all authority structures but not necessarily opposed to them in all circumstances.

For myself, I’d like to get to anarchy long term but I see more of a gradual transition happening. So I am OK with retaining some state and capitalist structures as intermediate steps with the long-term goal of eliminating them once we develop superior social systems.
