Q:
Jorbreaker's seem like a wasted idea
They don’t intend for you to buy it that way. It’s only there to make it look like the option is available. Giving a token option is what other games typically do to help relieve the failure of RNG. In those other games however, you can usually grind out what you want in a few days at the most.
They probably had more plans but never got around to it. For example, the food was probably originally intended to be crafted (rich coffers claim to contain recipes), using the candy.
