Oh I don't disagree. I'm sure there were a ton of people who had fractures that didn't heal properly on their own or with non-invasive care, infections that would be fairly straightforward with antibiotics today, etc. Certainly I've depended on modern medical care many times and probably benefited overall many others.

I've had serious fractures and taken antibiotics on a number of occasions. So I violently agree. But there's probably an age window when modern medicine is less important (outside of war and other especially dangerous activities).
