i do think it is worthwhile and i discussed this a bit in the piece Insurrectionary Anarchy & Revolutionary Organization...
i think struggle committees, mass assemblies, self-managed leagues, autonomous workers cells, informal work groups, workplace resistance groups, are all variations on each other what is important is working towards as direct and as unmediated forms of struggle as possible.
"some syndicalists hope to live in (urbanism, factories, specialization of labor, intensive agriculture etc)"
honestly i think this is a caricature inherited from the history of the old workers movement, contemporary syndicalists at least in the vein you cite thinking it is worth working with hardly want to keep alienated factories as a separate sphere of life, or specialized forms of labor...regarding urbanism it is really good thing for queer folks, and we obviously need to look into ways to be more at balance with the earth.
