The racks are even easier than the tub. You don't have to provide a lay-box... the entire thing can be the lay-box (just like you don't need a hide).
Not sure what you mean by "all that stress to not reap your reward".
Being a woman, it is always interesting to me that people treat pregnancy as a medical event. It is not. It's just a normal part of the life cycle. Hence, a lot of people prefer the midwife over an OB. The OB is only there when the event becomes a medical concern (complications such as pre-eclampsia, etc.).
Anyway, a ball python is the same - laying of eggs and seeing it through hatching is not a medical event - it's just a natural part of the life cycle. Yes, it takes a lot of energy for a ball python to incubate its eggs but if you have a healthy snake to start off with, it is not a big deal. The snake will continue to eat while taking care of the eggs to replenish that energy expended.
Many of us are not in it for the $. We are in it for the joy of being an active part of nature.
