Where was it stated that the Truth was immaterial? He is the embodiment of Alchemy, which makes him the embodiment of the FMA planet, and is destroyed if it is. Goku was a ghost when he fought Vegeta, and Vegeta knocked him out. Not to mention that in DB, Grandpa Gohan was a ghost, and kid Goku fought and beat him.
