I think the world would never accept that level of publicity. Besides, if all that information were published and put on blockchains, they would be littered with way too much with the kind of information the world wouldn't want. There are aspects of people that I want to know nothing about. It doesn't really even come down to social shame because I wouldn't want to know them even if they were well withing the spectrum of normative and statistical normalcy, but a sense of, say, mental hygiene. For instance, the mere idea of being a few clicks away from knowing exactly the kind of porn anyone searches online is kind of disturbing because it brings the most private aspects of those people's lives way too close for comfort.

Public blockchains like that will never gain any traction and our culture will never accept them. It's one thing what data some totalitarian state collects on its citizenry to do whatever it will with it without asking their permission. But democratic and open societies storing even remotely close to all such information on public blockchains, forget about it.

Interestingly, that information does exist in possession of private giga corporations.
