In fact, if Pokemon were real, then Shiny Hunters wouldn't be Breeders, but rich collectors who buy these from very lucky individuals.
Heck, I could even see a black market for them, like there is for rare art in real life.
Hunters like J tracking down shiny Pokemon and stealing them from their owners to sell them to rich collectors for an absurd amount of money.
