Exactly, not everyone. The UZUMAKI were capable of it, though.Rinnegan wasnt in question but stamina here, not every one can even bare rinnegan U_U
It was implied that the Rinnegan is hard to control. Nagato was an Uzumaki, who have great stamina, and thus was capable of using the Rinnegan.
Give Karin the Rinnegan, give Naruto the Rinnegan, give Kushina the Rinnegan... they can all handle it.
