Right, the problem in your model is that the doctors do! I am pointing out that this is a problem with the doctors, not the scan.
Scans are a tool, doctors are not allowed to use them rationally because it would be too expensive, so they don't use them. With an ideal doctor, patient outcomes would be better with a scan than without one, but my claim is that doctors are not ideal.
No doctor would order a full body MRI just to throw out the result in 99% of cases, because *it's too costly*
Obviously, the doctor does. Nobody was ever claiming that the problem with full-body scans was that patients were demanding biopsies!

Doctors are not ordering biopsies to salvage the value of a scan they just ordered.
