Isn't the way we decide what justifies intervention by comparing observational data, action and outcomes? Currently our observations are limited by many things including the cost and side effects. More frequent or better observations will improve the assessment of what justifies interventions.

That sounds more like a capitalism issue, to be honest. Treatment = revenue, so of course there will be unscrupulous individuals who will bend their oath and let patient anxiety drive care.

The trick seems like it would be to strongly incentivize waiting and watching any symptomless anomalies if further investigation is invasive. If you're getting 60 second scans every month then something growing will be catchable and something static or that disappears can be ignored until the next scan.
