as i write my silly little family abolition post i keep thinking of the segment in wage labour & capital where marx argues that capitalism as a system of production serves to enforce both production and non-production--i.e., when a factory is not profitable, even though it might produce something necessary, even if people might be willing to work there, they are actively prevented by private property--private property enforces the disuse of land, machinery, etc just as much as it regulates its use. and i think considering the family in those terms is really useful--because you can break away from just understanding the family as providing care (and therefore obviously a good thing, how could we abolish the family!) but also conversely as one of foreclosing care--if nobody will care for the child, or the senior, or the sick, or disabled, within the confines of the family, then the boundaries of the family serve to prevent anyone else from providing that care. much like industry is not a 'provider' of work, but a regimenter of it, so is the family best understood as a regimenter of care.
