I think some may not be able to afford new bows very often, and tend to either sell one to pay for another or trade one for another so that the dollars are kinda "swapped" if you will. That being said, I believe that is the reason some might shy away from hunting with them as the value will decrease with each ding and mark.
Although I try and be careful with my bows in the woods, (so I can resale if the need arises) I would not own a bow that I did not intend to hunt with,(collectors items are different) as that was what I feel they were intended for.
Plus a "pretty" bow gives me more confidence for some reason... :D
