So, i wouldn't fix this, it's too much effort and it will most likely stop subsiding, get a sliding bracket made for the gate to attach to so you can adjust it further.
If I did want to fix it, on the assumption that it's got a weak, or very shallow foundation, i'd try lifting it with an excavator or engine lift, then pour a new foundation and mortar it back down. This might not be possible, but i'd give it a shot in an afternoon before calling the sidewalk leveling guys.

What are you basing this prediction on?
From op’s post we know the column settled. He adjusted the hinge to compensate, and now it’s settled even further.
What gives you any reason to think it’s just going to stop moving on it’s own?

The fact that most foundation movement is caused by ground compaction, sliding or buckling, and outside of some very special circumstances, like building on a wet clay riverbed, the ground does not simply suck things down into it. The most likely reason it moved is that the original builder didn't compact the base enough, cause it's just a gate. Contractors rarely properly compact for gates, garden walls and fences.
But, even if it did, wouldn't you take a 14,000:20 bet on the $20 bracket side? I'd take that bet even if it was built in a swamp.
