Naruto has lots more chakra than normal people because he has naughty fox inside him, most people don't have naughty foxes inside them so they can't do that. Comprendo?

Besides when kakashi said that method would only work with naruto he was probably referring to all the people who were in the room at the time. Someone like kisame should be able to do it too.
