> Except the Tragedy of the Common requires a depletable resource of some kind, and unfettered access to it for people who have a vested interest in protecting their own supply but not the supply of others.

The depletable resource is user patience, i.e. how much shit they're willing to take before they start blanket-blocking ads. If every publisher stuck to simple, unobtrusive and relevant ads then readers wouldn't block them. But some publishers/ad creators/ad networks decide that they want more money so they make their ads more attention-grabbing, and then the others do the same, and then users get tired and start blocking, and everyone is worse off.
