> What if information could be revoked? What if information can't be revoked on systems outside your control? That's the reality, however many secret handshakes you do, blockchain, etc, eventually some person or process knows something and can do something with it (e.g. copy it). You could pull a gmail and say, there is no human in the loop, it's just a process of personal data ingestion and ads come out the other end. That might be more comforting if it was open source, but even open systems have things can be hidden in obscure technical details. The truth is, we are all human, including our leaders. Your average human is weak and susceptible to trading a vast privilege like having control of everyone's whereabouts for favors (e.g. money, position, control, sex, etc...). I'm a sucker for an open source process (e.g. robot) that would look at the data and tell us who needs to be quarantined, but again, you still have human technical people, with all their failings, controlling the system (e.g. source code). How much do you trust the open source process is a matter open for debate.
