Why do you believe that the possibility that people may be discriminated against due to their dna is a ringing endorsement for single-payer "medicare for all" health insurance?
Private insurance companies and employers (the two places most Americans get their health insurance from) may not want to pay for the higher costs associated with higher risk people like this. Employers would be especially susceptible to this sort of discrimination if proposed legislation allowing employers to demand genetic tests of their employees passes.

Because a single-payer health system (like the NHS) largely prevents this discrimination.
Seriously though, I quoted the reference exactly in my question, since I knew people would be touchy about the subject. Based upon other people's reaction to my question, some people are very touchy about the subject even when addressed elliptically and without pre-formed notions.
Thank you for your answer.
