Transparency is vital for regulation and control (see e.g. Seeing like a State) and the more opaque humans are, the harder is to control them, plan their actions, reason about their future behavior. How can you make a five-year plan for the whole country if you don't even know anything about anybody? Opacity is not going to work here. You would need a ton of very, very detailed information.
That's why China is introducing more and more measures to defy privacy - this is the only way their model can hope to work, it it impossible in the opaque-person world where no information about the person can be created. The article argues that privacy is not property, but the concept of privacy can not but lead to the concept of property - if you can have private thoughts, can you have private expressions? If you can have private expressions, can you have their material embodiment? If you can have the material embodiment, can you exercise control over it and limit the control of others over it? Oops, you just created private property.
