Tosha,
Looking at your question from a practical or common sense stand point the question the begs to be asked is: Who would buy a $40,000 animal and not breed it?
If a person considers their initial purchase price of $40,000 to be an investment it would be very unwise of them to allow that investment to sit idle for 10 years. Every year that the animal is not being bred is a potential loss of a return on the initial investment.
Considering the initial investment is a substantial sum of money, it is logical to deduce the animal involved is rare to some extent. As long as it is a proven morph or combination of various mutations the babies will help pay for the initial investment. Like another poster stated...by selectively breeding and holding back the offspring a person could end up with a very nice profit off that one animal.
Very few people have the money to spend $40,000 (or even $5,000 or $10,000) on an animal. Fewer still are those that have the money but actually want a snake of some type. I can not think of anyone spending that kind of cash on an animal "just for show" or because they like taking care of them. If that is the case a simple wild type animal from a pet store would serve the purpose just as well.
Let's face it: Every one of us on this forum will readily admit to enjoying their snakes (all of the various species we each care for), not everyone is willing to admit that money plays a part in the decision to keep them (for some they are simply pets). But, I bet a person would be hard pressed to find an owner of an albino, ghost, pied, pastel or any of the other "low end" morphs who isn't planning on breeding the animal at some point; if for no other reason than to help offset the cost of the morph they purchased. More so with the "high end" morphs and combos.
I can imagine someone purchasing a $40,000 animal simply because they love the color/pattern morph it exhibits and breeding it at least until it pays for itself. In this scenario, the owners intent is for a display animal, but they are wise enough to "get it for free" in the long run.
I tend to ramble at times, but I hope my reply made sense. Since, this was a theoretical question I only attempted to give a response that examined the question from a practical standpoint. I did not bother with "little" things like trade value, genetics, and market fluctuations. I think these are beside the point unless the question is more specific.
