Now think about all of the dumb, violent, ideological, illegal things that folks do.
No one wants their bowel/fertility/pregnancy/prostate/breast concerns made public or traded between companies. If for no other reason than health insurance fuckery.
To add a new point, what about the scope of trust here?
For the lifetime (which is?!) of the data do you trust:
- all the executives who make decisions on the data? IE direct policies but also indirect decisions like what budget exists for securing it.
- all the executive of companies who might buy the data or buy the company that has the data.
- all the technical admins of the originating company AND all the companies that might later have the data.
- all the governments that have legal leverage over the above companies
Honestly, I think this is a huge ask.
