Value is entirely subjective. My normal ball python is worthless to others but priceless to me.
I find this hysterical. This is exactly how life for humans works. No one wants me because I am a normal human. I was very lucky to find someone who saw my value and now takes care of me. Everyone is crazy for the morph humans. We call them attractive people or in the extreme celebrities. It may be wrong but its reality. I choose to accept it and move on.
It makes total sense to me an many others. If you want to breed a normal to a normal that is your business. I believe that the OP was talking about breeders or people who are doing it to sell the offspring. This is a very valid question.
I believe the albino BP started the craze. If you are referring to the fact that the normal ball python is the source of all mutations then if not for them 100% of us wouldn't be into ball pythons. I for one am quite fond of the normal type but I would dare say they did not start the craze.
Bond is a very strong word to use when referring to a reptile. Attachment is much more likely. I love my BP dearly but would give it up for many many things. I would save my cats first for instance, my girlfriend before that. If it came down to my car or my snake. You can have my snake. As much as I would like to stand by my earlier statement that my BP is priceless to me, I can't. It has a worth. I would be hard pressed to put a number on that worth but I can tell you that its less than $8,000 dollars and more than $100.
