> if it's valuable and nonexcludable (usually isn't)...
That right there is the problem, though. You are right that most information is "non excludable" (if that actually is a word).
But that doesn't mean it isn't valuable. That's an illusion, conceptually very much like clean water: almost free, but vital.
The stuff the wire services collect and sell (and that everybody republishes) does cost quite a lot to produce, and it's the backbone of the news ecosystem. It's subjective value is further diminished by its anodyne voice, making it difficult to picture the actual people reporting it.
Maybe the publishers do actually have a case for a new class of intellectual property protection. I'm horrified of the prospect, but within the current market dynamics, I don't see much of a future for quality journalism. Public opinion is critical of every and all publications, indiscriminately, and quick to use that as an argument for not subscribing. Wall Street may still pay for Bloomberg and the like, but Main Street doesn't see why. Maybe the NYT spent two or three million on some investigation. Once published, the information is delayed by little else than the time it takes the guy at BillingsMorningNews.com to switch a few sentences around.
With regards to ad blockers, you are right in that there is nothing in the law that should stop anyone from using them. But that's not really the argument. Nor is anybody disagreeing that ad tech needs drastic changes.
But fundamentally, the question is if blocking ads isn't hurting your own interests. Sure, there are many sources for the same information, usually. But the one you're reading probably has some small advantage, which is why you are using it. Once that publication folds, you have already lost something. And I'm not optimistic that the process will stop before it has drastic consequences on diversity and availability.
It also sometimes needs reminding that for an individual, news often seems like a guilty pleasure. But for a society, news is vital. Without it, you can't even keep up the appearances of democracy.
It's a tragedy-of-the-commons situation, obviously: blocking ads is vastly advantageous for the individual, just as fishing with the really big net is for the fisherman. But, thinking a bit broader, the question becomes: What's better – reading the news with annoying ads, or not reading the news?
