i don't think actual reconciliation is possible, and i long ago accepted that. but to give it a shot ...
by recognizing that a world dominated by mass society, capitalism and industry leaves virtually no alternatives for the survival of those opposed to said institutions.
it is no different, to me, than trying to reconcile utilizing the state (eg, food stamps, medicaid, roads, heating assistance, ...).
it is an ethical dilemma to some, but no longer to me (usually). i accept that i cannot survive in this world (the one created and perpetuated by those institutions) without participating to some extent in their processes and products. i am fortunately able to minimize that in my own life, because i have made huge changes in my life (and lifestyle?) in order to dramatically reduce my need for such. not unlike the point ba@ made in the comment above. and let me make clear that those changes were NOT a hardship for me at all. just an adjustment.
many of those opposed to the institutions mentioned (at least many i have known) are just as addicted to the comforts, amenities, entertainment, etc that those institutions provide, as folks not opposed. far too many people look only to big-picture, mass-driven (and mass-defined) changes; and refuse to make such changes in their own individual lives.
we all make our choices. hopefully they are thoughtful, and maybe once in a while they can even be truly reconciled with our desires.
it is my desire that ever more individuals would choose to simplify (and in the process, take far more control of) their lives and consciously reduce the extent to which they are dependent upon those things they oppose.
