You call it a scare tactic because you believe in medical interventionism. I respectfully point out one of the massive numbers of unexpected side effects of medical interventions.
Believe what you like. A thoughtfully considered medical intervention rescued my health. While patients need to be vigilant for errors and the best treatment is sometimes a matter of good fortune. there is no such things as "belief" in "medical interventionism." It makes as much sense as "weather forecastism" or "speed limitism."
Maybe you should understand what medical interventionism means, before typing out a meaningless and unrelated argument.
So if you break your arm…
... you go to a doctor to have it set and casted. Unless the break is so minor that you can self-treat with RICE. You don't have to be a passive recipient of a medical treatment flowchart.
