While I'm open to the idea that "certain things XY can't be built under system Z", I think that this feels like one of those things that should be no?
My question re: non-profit co-op-ey things is usually "can this thing run sustainably by enriching users" rather than the usual "can this thing run sustainably by enriching shareholders".
A super low-overhead social network for ecology feels like it could easily fit that bill. Lots of democratically run social networks running today to attest to that.
