Did you not read what I said? Loki being that strong is rational, he has a legendary fruit with a world-ending reputation stacked on top of his already impressive base.
The guy killed an underworld gigantic bear by beheading it, survived kilometers tall fall and climbed the adam tree the day he was born
Even for natural born monsters like Big Mom, Oda waited for her to be be 5-6 before having her pull prodigy feats.
Now you consider that he's the last remaining living ancient giant, and that even among ancient giants his eyes are unique in the OP world (even the eyes Imu have are shared by other characters like Mihawk or Zunisha) then him being this strong isn't really an issue.
What would really fuck up the powerscaling is Shanks beating Loki 1 vs 1 , except if Oda later reveal Shanks was hiding his real strenght until Luffy managed to awaken his fruit (rip Mihawk in that case) cause Nika is needed to take Imu down @Fujishiro
