Only kill for God and not for food

Leviticus 17:3 Saya, “What man soever there be of the house of Israel, that killeth an ox, or lamb, or goat, in the camp, or that killeth it out of the camp,

17:4 And bringeth it not unto the door of the tabernacle of the congregation, to offer an offering unto the LORD before the tabernacle of the LORD; blood shall be imputed unto that man; he hath shed blood; and that man shall be cut off from among his people:”  Ummm, wont the people get hungry if they can’t kill these animals for food?  I guess god only wants the animals he created to be killed for his pleasure.
