I upvoted your opinion, because i think it discuss worthy. You argue, that sociopolitical constructs can not be made that contain corrossive elements. I think, some of the democratic institutions proof the opposit. As in biology containment vessels can be constructed to withstand quite extraordinary corrossive circumstances. The strategys against the corrossion are constant renewel (disposing of counter-measures), counter agents to corrossion (keep the secret services busy with infinite clutter), rerouting of corossive elements (avoid giving them a attack surface- for example by distributing the hidden app via a virus/non visible release group). Finally, and thats the beauty of it- the Centralizers may be the undoing of there own system- after all its usually monocultured (very few os-systems), has a very centralized single point of failure- and the greed involved usually corrodes even there tools. Thus if a NSA backdoor guns down the internt, and this app would still be up, i think on that day, my suggestion could pick up the pieces.
