If the scale of the danger at large is too big too ignore (as in, the entire planet or all life could be at risk), then Knuckles might leave his duties to pursue the bigger threat at hand.
While the "greater good" argument has sense, and was even used in the Archie continuity as memory serves, a problem arises in the simple fact he either has to leave the Emerald unguarded or take it with him, thus causing the Island to fall. I'm confident Knuckles is well aware of the fact the Master Emerald needs protection for a reason: it has such immense power and capabilities that it can't be allowed to fall into the wrong hands. So it's reasonable to assume he'd have some sort of backup plan to keep it secure whenever he ventures down below... the problem is Sonic Team's never elaborated.

3. If the Master Emerald is not in threat of being stolen again, then maybe Knuckles can afford to step away for a while. After trying to many times, I don't think Eggman cares about the Master Emerald anymore; especially considering how much messing with it backfired in Sonic Adventure. Eggman trying to steal it again in Sonic Adventure 2 just seems forced, but he probably did it for insurance against things like Shadow and Bio Lizard/Final Hazard rather than his usual reasons for stealing it.
Based on the dialogue in Sonic Adventure 2, it sounded like Eggman was expecting a Chaos Emerald, but found the Master Emerald instead. He more or less seemed to just shrug about the situation and figured he may as well take it while he was there. So it was spur of the moment; as such, we can conclude Eggman has indeed given up on stealing the gem based on the main titles.
Which I find incredibly surprising since Knuckles is down on Earth half the time anyway so it's strange a man of his genius hasn't dispatched some sort of small task force to "borrow" it while Red is busy elsewhere. Then again Eggman does forget the minor details sometimes...

Isn't that pretty much exactly what happened in Sonic & Knuckles? Knuckles is off setting up booby traps for Sonic and while they are distracted and fighting Robotnik finally finds the entrance to the Hidden Palace and steals the Master Emerald before the final levels.
Hmm, somewhat, but I meant a more comprehensive trap system. Knuckles' system was horribly flawed since he had to be present to trigger each one; my concept of effective traps would allow him to leave the island, whereas whoever stepped within so much as a hundred yards of the Master Emerald would find some bad fate or another awaiting them. His trap system in Sonic 3 was very crude and ineffective as it necessitated he be there to activate it manually.

Yeah, the Master Emerald mass-shifts in Sonic Adventure 2's Last Story, so it looks like he literally pulls it out of his ass. Whether that's a presentation choice or an actual ability of his I'll leave to fanwankery.
I think it's safe to say he can most definitely carry it around with him (he has a reputation as the strongest, even), though the actual size shifting likely is just presentation. It looks less awkward if he pulls out a medium-sized gem versus one that's gigantic.

He's also got his innate ability to track it down as seen with the radar he's had every single other time it gets shattered into pieces, so I assume even if some low-level crook archeologist tried to sell it on the black market he'd just be able to track the thing down and pummel the responsible party anyway.
His (apparently) psychic link with the Emerald definitely has its uses, as he'll know if/when the Emerald is in danger (as he did in Sonic 3&K) from afar. My main problem is that even if he carries the Emerald with him to keep it safe, logically that means Angel Island falls into the ocean. From what we've established, this is an undesirable outcome, so it leaves us with a bit of a problem: Knuckles can't simultaneously have the emerald on his person and keep Angel Island safe in the heavens.

Knuckles also isn't just bound to protect the Master Emerald, but oversees the entire island. He doesn't need to be within seeing distance of the Master Emerald to do this. As a bonus, he can shrink it and take it around with him if need be, as seen in SA2.
That's where a problem arises though: how can he adequately protect it if he's halfway around the globe? The Emerald is safe of course, but if he's not on the island there's nothing to keep it safe. Unless he has some teleportation ability or has set up automated defenses/assistance on the island, there's nothing there.
Seems far too utilitarian for him to just write the island off on the basis of reclaiming it later, I'd think.
