Investment in commons is something rich societies do. If we're predicated on a collapse hypothesis, the rich will focus on survival and power. That returns us to a zero-growth, zero-sum environment, which almost linearly leads to militarization. (If I have a choice between investing in research or buying munitions, and I believe society is about to collapse, I do the latter.) Between an army and a law defining XYZ as a common good, the army wins.
