Hamura got his power by awakening it from within himself, as opposed to an external catalyst, as there was none mentioned. There isnt much reason to believe he was particularly old when he got the Tenseigan and accompanying abilities.

Lack of TSB doesn't mean lack of 6PSM. Naruto had 6PSM active when he kicked Madaras TSB away from but they appeared and disappeared with the 9-Bijuu cloak. Even though the TSB is a 6PS technique it seems to require being cloaked in the chakra in some way. Similar thing happened with the Tensaigan Chakra mode.

With regards to the eyes and the body, its figurative and literal. Sort of. The way i see it is that the Rinnegan is the dormant ability of the eye as of Indras birth. 6PS is the dormant ability of he body as of Ashuras birth. Until they awaken, Indra and his line would only have MS at best, while Ashuras line would have the longevity and life force (maybe a knack for Sage Mode cuz Hashi had his outta nowhere total speculation for him though). Hagoromo giving his power doesnt necissarily come with all of his abilities. The patterns imply that he is only passing on his chakra (and with it 6 Paths chakra). The 6 Paths chakra would activate the dormant ability of the corrosponding bloodline only.
