Is it your contention that if an obese, not-runner who views walking as a form of exercise were to start running, the immediate effect would not be knee injury, but actually strengthened knees, on the evidence of a study comparing recreational runners to people who are obese and don't move at all?

No. Every exercise regime must include a ramp up period. If I started training like an olympian tomorrow I'd be in the hospital by next week. Same thing if a couch potato tried to insta jump into my workout routine.
My contention is with people who don't even try running because they're worried about a hypothetical injury 30 years later.
You can also adjust your training volume if it becomes a problem. For example I got an achilles injury because it turns out 3 marathons in 1 year was too many and I needed to put more focus on recovery.
