Am sure there’s a very real possibility that some shady data brokers will ultimately gain access to the treasure trove of data before long - and am sure that in our capitalistic world healthcare and insurance companies would happily pay for access.
In the USA. In Europe and such, I'm not saying it's zero chance, but it's extremely unlikely. As Europeans don't rely on insurance for healthcare, but we use government for that :)
( the exception being, if you want private insurance if your government provided one isn't enough)
Not to mention it is illegal and not even an illegal money makers.
