I get that, you get his Chakra you get his "powers" per say. But then why is it the only way besides Hagoromo giving it to you himself or eating a fruit of the God Tree? Hagoromo did neither of these to unlock his Rinnegan. As far as I am aware that is. (Because I mean it's kinda hard to give yourself a KG/KT you don't have, and I am PRETTY SURE he didn't eat a fruit from the God Tree.) That's like for example, someone builds the first car ever, and you can either get it by buying (which would be impossible since it's a new thing hence expensive and rare) but you cannot build one yourself, because reasons.

Basically the only people who had the genes required to produce Rinnegan chakra are Kaguya and Hagoromo nobody else has inherited the Rinnegan genes so the only why to gain the Rinnegan is to aquire the DNA or chakra of Kaguya or Hagoromo.

Kaguya is sealed away thus inaccessible and given that Hagoromo took precautions to prevent Kaguya's escape like the stone tablet he likely ensured his body was destroyed after death thus none of Hagoromo DNA being available so that left Hagoromo's chakra.
