Adrian;

I'm afraid I can't agree with your categorization of de-identifying data. A lot of the work that I do with de-identification is in the health sector where de-identified data is how individual privacy can be protected while enabling medical research (see here and here). Depending on the jurisdiction that one is in, the process of de-identification may be a 'use' of the personal information for which some kind of consent or legal authority may be required. Setting that aside for this discussion, once de-identified the data is no longer 'personal' information so providing that information to a researcher can hardly be called a disclosure.

Since I live in a country with a single payer medical system, I don't think I want to wade into a discussion of the expenditures in the U.S. healthcare system. We'd best leave that to a another forum;-)
​ ​
What I will say is that I sit on a Research Ethics Board that deals with a lot of clinical trials for cancer drugs, where many of the trial sponsors are drug companies. One assumes that there is a lot of money at stake for the companies, and the drugs are often very expensive, but all the trials are based on informed consent. I believe that this is normal in the U.S. as well.

And finally,
​I'd point you to this story here in Toronto about a 'black-box' in the operating theatre.​
​ It is an experiment for recording what happens during surgery, to enable quality controls and reviews in much the same way that black boxes are used in aviation. This seems clearly sensible from a process improvement point of view, and the information collected could be defined as personal information about the patient. This one will be interesting from a privacy perspective if it becomes standard practice.

The point of the above is that not all information about the person has commercial value. It's almost always of intererest or concern to the person who it is about, and in that sense has value. It may be useful for others for research or other reasons, but not in a commercial or a transactional sense. We need to be more nuanced, it seems to me, in where we apply the principles of VRM. This is valid for commercial relationships and exchange, but shouldn't be a universal rule for all information exchanges on the Internet.​

This is most evident in US healthcare where prices are opaque and quality measures non-existent. Healthcare supports a growing market for de-identified data that may well exceed $20 B at the same time that US consumers are being overcharged by $1 T compared to 10 other developed economies. Does anyone really think these two numbers are unrelated?
