I hear part of the Chinese miracle of central planning is that they have almost full knowledge of everything everyone is doing in the economy. In contrast, in the west, where we optimize for personal gain, you can get a lot done by throwing up barriers and creating friction. We also pretend/believe our governments use all data against us.
My gut tells me that cryptography and clever use of time and location can be used to use public data for specific purposes alone.
You could for example construct security cameras with sufficient encryption that only a judge can request access to a specific chunk of time and has to provide a specific case number.
It might even be possible for the judge to request a specific thing from the footage like time stamps and licenseplate numbers not from people living there or even similar faces and devices seen around similar crimes.
I don't want the specific time stamps and locations made available buy I don't see great value in keeping my annual toilet paper purchases secret or how many km I need to travel to purchase shoes.
Maybe (when seeking) we should get proximity push notifications for job offers that fit our resume.
I mean, we should explore the boundary between anti-personel computing and useful application. Maybe things are worse than we think, maybe they can be made mutually beneficial.
