That isn’t what the tragedy of the commons is. It isn’t about something inherent in having a shared resource that dooms it. It is about the idea that when there is a limited, shared public resource, individuals making rational self-interested decisions will often lead to a situation which no individual would choose. That doesn’t mean it always has to end in tragedy, though. It just means you can’t just go fully “laissez faire” and let everyone do whatever they want, and expect the common to be preserved. The only way to protect the common is to take some sort of collective action; pass a law that limits how much an individual can take from the common, or set a quota and allow people to bid, etc. The collective action doesn’t even always have to be a legislative action; you could create a taboo around using too much of a common, or use social shaming to get people to only use their share. The point is that you have to take SOME collective action to prevent the tragedy.
