I don't disagree?

Exercise is best used to build muscle mass and is not very effective if the goal is a caloric deficit. You could run, some people love doing that, but most aren't able to do this consistently enough - and the more overweight the more injury prone.

Walking works just as well as high intensity cardio it just takes proportionally longer. You're paying for your extra weight and lethargy with time. However, everybody (who can exercise at least) can do it, and it works.

Going from sedentary straight to beast mode rarely works.

And most people are in fact overweight. Walk for a month or two to shed weight, improve mood, and form good habits - then progress onwards from there. Maybe throw in pushup sets every mile or get down to the park with the bars, 'etc.
