I don't think Naruto's method of training to be a shortcut, yea it speeds up the process but it also has a cost... and also it's not something anyone can do...
I mean first the huge chakra reserves required to use the mass shadow clone jutsu, to create 1000 cones, and secondly you also need the stamina to withstand it, i mean all the stress and everything one clone has it goes back at Naruto 1000x. So it is not that easy as it looks... just as Kakashi said, it's because Naruto is who he is that he can use this method...
Just as someone said it would be a shortcut if he skipped some of the steps of his training, or if shadow clones had no side effects or used no chakra... when it clearly does and remember that it is a forbidden jutsu exactly because it uses up allot of chakra.
