I'm struggling a bit with your second paragraph. I think there's something interesting here, but I'm not quite clear on your argument.

Data is the opposite of the paradox of value, in that one person's data is completely useless, but each additional person worth of data adds a greater and greater marginal utility (probably not linearly so, maybe an s-curve or something). Is this what you are saying?

I haven't read the book you link so perhaps that is why I misunderstand.
