Because over-testing, over-diagnosis, and over-treatment are all associated with harm.
People bang on about early intervention, and it's useful for some stuff, but for a lot of stuff there's no evidence of a reduction in all cause mortality.

For example, we currently do not have a diagnostic test that can tell the difference between a virus or bacteria so physicians prescribe antibiotics just in case. If we did then we could reduce the use of antibiotics. Genomic sequencing won't help this case specifically, but sequencing at the proteomic or metabolic level may.
