Which has nothing to do with the biology of Collagen fiber growth. Damaged collagen structures can repair themselves in cross-linked fashion that cause them to be tougher without being any longer; making future attempts even harder. The science is pretty clear on that; its not an analogy to anything.

Actually, most manual exercises are at higher intensity than hanging. Jelqing can apply a degree of intensity that is about never reached through hanging.
I would disagree on that. Given the high amount of void space in the penis, the actual cross-sectional area of the tissue is pretty small. 10+ lbs of hanging is going to create much more stress than a couple psi of internal pressure from forcing blood into your penis.
