Can you beat Earthbound without using PSI or items?

#CanYouBeat In Earthbound, you play as an unusual kid who uses psychic powers and is skilled with weapons. Have you ever questioned if you could beat Earthbound without using any PSI, equipment, or items. Can a regular group of kids with no unique traits defeat all the evil in the world? Watch and find out (or just skip to the end if you're lazy).
