Agreed. I'm an extremely fit runner doing 50+ miles a week and almost all of my runs are in a super easy zone that is equivalent to an uphill walk for most people. A lot of this has to due with well developed biomechanics, but also superior vo2max.
Most health focused runners should be walking at an incline or running downhill except for 1-2 high intensity interval days. There are huge benefits to low intensity activity and higher doses are almost always better. The sort of intense, grueling runs that most people do are likely counterproductive. It's like running a race every day as a workout. It's just not sustainable and unhealthy at high doses.
(Of course, if the goal is to be a runner and not simply be healthy, you'll need to push your body to a point where running is like walking but it takes a long time to do correctly.)
