You sound like RFK Jr. Yes most people in our modern world don't get enough exercise, but it's not a panacea. Exercise, sunlight, and clean eating alone won't do more than nudge most chronic illnesses. Hell, the latest on ME/CFS is that exercise can actually worsen symptoms.

"All I needed was exercise and/or a healthier diet and I felt great!" folks were not truly ill to begin with, just slacking. There's a huge difference, and insinuating otherwise is a giant slap in the face to those who've tried these things (and likely so much more) and are still struggling with debilitating health issues. To use a car analogy, regular oil changes and premium fuel won't compensate for a broken axel.
