People keep animals for all different kinds of reasons and their reason for keeping will reflect their view on the matter. Simple as that.
I only have one python and that's all I want and I'm happy with it as a specimen of a pure locale and an example of what you would find in the wild. I respect it and I respect the time it's taken for them to evolve the patterns that they carry and I see no need for it to be any other way.
That's great, I think that's a really lovely attitude and it's closer to what more people had when I was first keeping herps back in the 80s. I miss those days, and I wish there was more of that spirit still around.
However, looking at the reality of the present day, if I had 1000 bog standard Children's Pythons and 1000 albino Children's Pythons, and advertised them at the same price, I'd sell out of albinos and have a huge load of further requests before I sold my first regular one. If I had 1000 typical Jungles and 1000 jungles with brighter and cleaner yellow than anything you'd ever see naturally, against perfect solid black, I doubt I'd sell more than 5 typical ones before I'd sold out of the speccy ones. Same goes for any species.
There will always be a huge diversity of people doing different things for different reasons, but the vast majority most want the prettiest, healthiest, or most rare.
Would you honestly suggest that a python breeder not select the prettiest babies for the next generation?
