From what I could found, billionaires die on average at ~83 years old. ( https://strygin.substack.com/p/how-billionaires-die )
It's not far off what a decent health care system is able to provide in most wealthy countries. It's even somewhat lower actually.
It's difficult to assess the risk factors, but in the end, I have the feeling their additional medical staff and their ability to "cut the queue" (S. Jobs-style) just barely offsets the additional common risk factors (stress, long hours, segregated life), specially if we compare to the upper-middle class.
In the end, there is no magic $100M pill giving you 10 more years. And in truth, access to food, drinking water, a non-toxic environment and really basic healthcare & medicine (vaccines, antibiotics) probably already brings you at a fairly high life expectancy.
Every system that exists as a black box is more understandable with more sensing, not less. Our bodies are not special.
It's also ridiculous that the proposition goes like:
1. Doctor knows some tests will flag tumors or variations that look weird and that we shouldn't then go investigate all of them
2. Doctor shuts off their brain and will then investigate all of them by doing invasive procedures
Just knowing how many such variations there are and if they grow or not is useful information. But the doctors pretend like they are super smart before the test and super dumb right after.
Ask yourself, do you think billionnaires have yearly MRIs or that they wait for later because the doctor and themselves will be anxious? It's an argument that treats regular people as stupid.
If you are a billionaire you also have a doctor with the time and expertise to properly evaluate the evidence in a Bayesian framework, and you have time to talk to them and understand and implications. That isn’t scalable.
Also, it’s quite likely that billionaires are having lots of unnecessary procedures and that harm is being caused. The mri scans are not the reason they live longer!

With perfect humans in a perfect society, maybe. But such is ignoring the elephants in the room here, from the actual experts on the topic.
Case in point, doing that during COVID I think amplified the wave of antivaxxers and medical denialists. Which itself had in my opinion a way worse effect on global health than almost anything else recently because now you have to convince a number of people to trust the medical system again.
