hagoromo just awakened people's abilities to mold there physical and spiritual energies together. and clearly kaguya already had chakra before eating the fruit. otherwise she wouldn't have been able to blow people up without touching them

on a side note. the fact the shinju was draining the world of natural energy makes me speculate that hashirama's senjutsu was because of his wood release ability.
