"Real-world physics doesn't work in Naruto. Wood Release, Water Release, Earth release all casually defy conservation of energy. So yes, users of chakra can create mass from nothing. Now i'm going to laugh really hard as you just made me imagine an earth release user eating a few cubic meters of earth to fuel his jutsu."

u meant conservation of mass, and not energy, by the way. but u see my point, just as I see urs, so im good.
