People need to understand that rinnegan is an otsutsuki doujutsu and the fact that hagaramo divided his chakra and abilities among his sons. Indra had the eyes while Asura had the body but how do you get Indra's chakra from Madara or sasuke? By using their cells? Lol we'd have lots of sharingans if using uchiha cells grants everyone normal a sharingan. Since its almost impossible to get hagaramo's chakra, indra's and ashura's is the available option but sharingan acts as a foundation to lay those chakra.
