>Like 80% of the Pokemon with stone evolutions can only be caught either at Celadon or after Celadon, so what exactly is the challenge in getting them to evolve?
There was none, that was the point. The challenge wasn't evolving them, the challenge was training their pre-evos high enough to get the moves you wanted BEFORE you evolved them. With the exception of the Eeveelutions, all the store-bought stone evolvers stopped learning most, if not ALL, of their line's moves once you evolve them. Clefable/Wigglytuff were the same with Mt. Moon's moon stones.
You weren't supposed to evolve them as soon as you could.
