But this is a problem society is going to have to deal with head on. Trying to protect your DNA is futile. Maybe you shouldn't post the results, but it doesn't exactly take a lot of serious interaction with the medical system before they're drawing blood for something or other. And in the very near future, they'll probably want to start sequencing your genes almost as often, as we enter the era of being able to tell from your genes whether a given drug will be effective or not, etc.

I don't deny there's a problem, but this is at best a several-year stopgap, not a solution. You will want them to sequence your DNA to determine which cancer drugs will work best when you are sitting in an office with cancer.

The problem is that medical insurance is currently uncomfortably between actual "insurance", coverage for unknown and expensive catastrophic events, and "health care", a program for spreading the costs of health care between many people to equalize the burdens and also sort of cover the insurance use cases. Expanding our knowledge of what you might get starts breaking down the premises the insurance system is based on.
