This just kind of struck me today, and it's by far the most logical explanation for why Loki isn't in Hybrid as of 1181.
I think Loki's Full Zoan and Hybrid forms are like Gear 4/5: he can't use them without exhausting a lot of his stamina.
(I believe the energy Devil Fruits use is Haki, which is why Gear 4/5 and other Awakenings like Law and Kidd's drain you, and why Law and Kidd don't have strong Haki: their fruits take up too much of it).
Loki and Luffy are both Sun Gods, so them having a similar cooldown fits, and we have narrative evidence for this cooldown existing, already.
Loki is already a massive individual, who wields a ton of power.
He was an absolute monster before gaining Ragnir and Nidhoggr.
Using both of these Fruits at once just drains him, and he's seriously injured, anyway.
After Loki uses his Hybrid, he'll most likely be out of commission for a while.
I expect this is when outside forces will arrive, since the rest of the new world is not going to let the world government just take over the island, knowing how much of a pain, it would be for the world government to actually rule Elbaph.
Once Loki goes down, other top tiers will show up. Dragon, Shanks, Cross Guild, maybe even Kaido and Linlin.
I believe that this cooldown is absolutely necessary, because Loki just breaks the entire verse without this limiter.
This also quells some arguments against Loki joining the crew.
If he can only use his Zoan forms sparingly, and can't use Haki afterwards, Sanji and Zoro legitimately have a chance to match his power, because both of those characters have no cooldowns.
I'd imagine Zoro is in charge of helping Luffy when his cooldowns kick in, and that Sanji will aid Loki with his cooldowns, since they have similar storylines with their parent's death, mother's love, rejection by their biological parent, and and aspect of them that makes others view them as inhuman (Sanji exoskeleton, Loki eyes).
I doubt Loki will join the crew anytime soon if he does it all, but his Zoan forms draining his Haki and forcing him into cooldowns like Luffy's Gear 4/5 do open up the possibility of him joining in the future.
Loki realizes how strong Nerona Imu is, and is saving his Hybrid Zoan for when he truly needs it.
