Ok but now the argument shifted from "More MRI = bad" to "More MRI = okay as long as doctors do a good job and have enough time". I agree with that. My point was just that it's possible to get to a point where everyone having yearly MRIs is doable because the issue isn't with more information in itself, it's with doctors not having enough time for the patient.
But now your argument also depends on no opportunity costs for doing unneeded mri, or infinite medical resources.
As I said … we really don’t known how much harm billionaires are suffering (sob) and there are much simpler explanations for their longevity.
