I feel what happens more often is *specific sociopathic actors* take advantage of the collective resource and attempt to claim it for themselves, often destroying it in the process.
common land in england was not overused and depleted, it was enclosed, deliberately, by powerful actors, and taken away from commoners.
anarchic projects like the Paris Commune, Kronstadt, Catalonia, Rojava, Chiapas don't collapse under their own weight because they are not sustainable, they are destroyed from the outside, deliberately, by violent people for whom the success of an egalitarian society is an existential threat.
foss and the open web are not straining under the weight of individual over consumption, they're being attacked, deliberately, by malicious actors seeking gains and power.
