I agree, because as you mention, the curators are struggling too, as well as artists. Hell we're all struggling, artists or not. So in my opinion, this "heavy curation" or "rise of the curator" (even the "everything is curated" symptom) signals a sort of precarity, a loss of authorship and ownership experienced by ALL individuals (artists and curators, teachers and construction workers, etc.); it's an attempt to regain autonomy when a neoliberal capitalist economy has strippped us of all of our worth. I think it's important to avoid a situation of artists pointing fingers at curators and vice versa--these two groups should be allies, and I would even further argue, they should ally with non-artists/other precarious laborers.
The institution bit is a little more tricky, but related I think. Institutions are in crisis because people are in crisis. Curators (people) have a unique role in the crisis, hopefully figuring out some sort of solution, resolution, or new direction/future.
