I think this is yet another instance in which the underlying assumption is that it's the same for all of us and I don't buy that. I have no doubt endurance activities are risky for some, neutral for some, and beneficial for at least a few.
I'm NOT saying endurance activities are right for everyone, perhaps only a small sub-section, but if they come naturally to you they can be important for your body and mind. Not everyone thrives on high intensity either. You might go out for track but I'd go for cross-country (and with no encouragement from me, both my son and grandson made that choice.) Our species conquered all types of terrain/environments and we don't all have the same talents and needs.
I am only n=1, of course, but here I am at 65 with noticeably more flexibility and strength than many of my peers. I take no prescription drugs either and if I have any serious health conditions they haven't made themselves obvious.
As a young child I was already doing what would be considered endurance walking plus barn work. In my teens I was still working in barns and walking about 2 hours every day. In my 20s and 30s I enjoyed long-distance hiking, 15-20 miles at least once per week and every day on vacations. In my 40s I was riding my bike 78 miles every Saturday with shorter rides and line dancing/aerobics during the week. I did a 2-day 150-mile biking event and outperformed many younger riders. Etc., etc.
Unlike "normal" people, it always took me 40 minutes to an hour to fully warm up and then I was good for 6 hours or more of hiking/biking/horse riding. I didn't have to follow an insane training program, either. If I was fit enough to go for an hour I could go all day; I'm convinced I have nomadic genes among others.
It's true I have significant wear (translation aches and pains) in all joints including my spine, but it's also true that I walk with a bounce like someone 10-20 years younger. The aerobics turned out to be a bad idea because my joints loosened too much, but my muscles thrived on mild lifting and I still carry groceries and laundry around without difficulty.
Here's the thing: I never smoked and never drank heavily so the greatest risk to my health has been binge eating of highly processed foods. Exercise always steered me toward healthier food so I'd say it was a good thing and short, intense activities just weren't right for me.
