Your reasoning is...well, not very well thought out at best here Joe.
The objective of keeping an animal in captivity as a pet is to improve on the situations that they would encounter in the wild.
Regular feeding opportunities may not arise in nature but we can improve on that in captivity and in effect, optimise a snakes natural ability to grow to sexual maturity in a short time. Snakes in the wild may take much longer to get to their breeding weight but we can improve on those conditions in our homes.
A chosen nesting site may dry out in drier conditions or become waterlogged in an unseasonal downpour but in our artificial incubation environment, we can monitor and control this so that the best possible scenario in nature can be replicated in our homes as well.
These are just 2 of the situations we make better for the snakes to ultimately bring gains to ourselves if breeding is an objective.
Removal of predators, removal of parasites, comfortable temperature ranges....these are but a few of the modifications we make to improve on what nature can offer a snake in the wild.
I don't see how incubation in an airtight container is an improvement on what mother nature offers?
