Not all anarchists are primitivists. Ironically, the person who created the modern green movement, Murray Bookchin was originally a techno-utopian anarchist before dropping the anarchist label later in life.
A lot of contemporary libertarian left thought inherents that same "Post Scarcity Anarchism" subtext, if not explicitly, but manifested as the idea that all praxis is harm reduction until the material conditions for post-state civilization are met. Revolution is just a particularly violent, abrupt, and uncertain form of harm reduction compared to the state capitalism and democratic socialism models.
