I won't speak for all runners, but for me, running with incorrect form is a fast way to make myself immobile.
I've had bad knees since I was 16, with surgeries to boot. Even 20 minutes of running used to require an ice pack for half an hour, and walking would be difficult for at least the next two hours. I suspect it's somewhat genetic, since both my father and brother also have frequent knee injuries.
Barefoot running has allowed me to increase both my range and my speed without causing any pain or swelling.
