in the end, susanoo is created via the users chakra right? that means that user MUST have enough chakra in his body in order to use PS :/

massive amount of chakra just means it causes the user to expend lots of chakra for instance when kakashi used the sharingan back in the day it used lots of his chakra and caused him to be bed ridden for weeks with excessive use. the same with susanoo. Excessive use of susanoo caused the user to use up massive amounts of their chakra reserves itachi never was one with a large chakra reserve. being equal to kakashi in chakra reserves and having the same stamina.
