Could you sell your own personal data at auction? Maybe. It depends on who is buying the info and what they stand to gain or mitigate their risk if you want it in corpo speak.
Car insurance already does this by giving discounts for having a gps tracker connected to your car. These things give data like location, speed and g forces. If you drive outside of their parameters your rates go up. So your driving data is worth whatever the discount they give and that’s just a fraction of your data.
In a way I would feel more comfortable with china having my shit posting data than an American company. At least if china has it, there is slightly less of a chance of them selling the data to a data set deanonymizing company who in turn sells my data linked to me to like an insurance company who jacks my rates because I said their CEO should get Luigi’d. What is china gonna do to me if I never go to China and exist largely outside of their sphere of influence?
