I can see thinking the tragedy of the commons is capitalist propaganda if you think there is a hard line between people and corporations.

The North Sea fishing industry didn’t collapse because too many of the proletariat wanted to do a lot of fishing, it collapsed because thousands of people organized into dozens of groups that systematically overstrained the ecosystem. Because those groups wanted to make more profit for a small group of hundreds of people. Everyone involved was acting in their rational best interest with no oversight or regulation guarding the big picture view and it caused everyone involved to destroy their livelihoods. Other than the ones at the top who’s livelihood is/was consolidating profit of course.

The tragedy of the commons isn’t about how it’s an individual’s fault or responsibility. It’s about how larger groups need disinterested guardrails for long term higher quality of life.
