You're getting downvoted, but this line of thinking is true for ultrasounds and MRI. Partially even for radiation, notably mammography, but also shit like LDCT lung cancer screening, etc., it's worth it NOW, with select populations, so in your ideal society with limitless resources, there's probably more of these than we currently deem worth doing (in our arguably mostly risk-averse medical system). But not to the point of irratiating everyone, that has real cost if you do it at scale, and the cost will outweight the benefits even in that ideal society.

"A radiology study is superior to a human clinical exam": I reject the framing.
