Dude, you ever see what happens when someone comes out of a pokeball?
Sure, people in pokeballs don't age, don't decay, any physical ailments stop progressing. You can stick someone in and they'll "live" until the end of time. But you can't bring them out again without frying their brains. Nobody's ever been able to store human consciousness in a pokeball. Which is a huge blow to the medical and transportation industry.
It's been tried and tried and tried. Zero success. Every test subject was permanently burned out. Either they're insane, mentally disabled to the point where they can't function alone, or they're totally catatonic.
There's just something about our brain structure and mental makeup that's incompatible with energy storage.
Eventually, every region mutually agreed to ban research and anyone who captures another human in a pokeball is tried on the same level as murder and treated accordingly. Go up to a random Kantoan at the scene of a Pokemon attack and ask why we don't just stick that beedrill-victim in a pokeball until the ambulance arrives and you'll be lucky to get outta town in one piece.
