Everyone in the world, or even your country, is not your neighbor, that's a specific group of people.
I disagree, the much simpler interpretation is that everyone is either our community or our neighbour.
Jumping through hoops to define what might or might not be a neighbour just sounds like trying to find loopholes.
Gonna apply Occam's razor on this one.
Out-group people are not inherently enemies to Ling Qi like they are to, say, Sun Shao, but the whole world aren't part of any of her in-groups either.
This very insight is what would define how you should treat your out-group.
My position is that this insight should push us towards taking the stance that we should be pursuing consensus and convincing people to agree with our policies rather than trying to force our will on anyone without very good reason (e.g. they're committing crimes).
I agree that this will be limiting in how we can bring about change, but I also feel that is good.
If we're using spy/dream powers on everyone who isn't our kin or hasn't proven to be 'good neighbours', then we're just becoming the same kind of monster who uses brute strength to make others submit.
The flavour of power is different, but it sets us on the path where we can use our power on any neighbours simply because we have that power.
By saying that spying makes us a bad neighbour, we are saying that we should only use our power when there is just cause.
We want to change the emerald seas, and unfortunately that may mean being poor neighbors. Making demands of those who otherwise extend respect.
We want a world where our successor can take this insight. But I don't think we are there.
This is actually the most convincing argument so far. And I agree that this will make changing the Emerald Seas much harder.
But even so, I think that this hard path is something we should take.
Because by taking this insight we force ourselves to not be just the next conquer or revolution leader. Someone who, while being a better/kinder, leader, still just fits the mold of 'power gives you the right to demand and dominate'.
This insight would instead take us on the path of changing the Emerald Seas without demanding or dominating, without forcing others to submission
The path will be harder, but if we succeed, we will not just be filling an old mold, but redefining the the very mold of what it means to be a leader.
As for waiting for a successor to take this insight, I don't think we can rely on luck that much.
If anything, we should take this insight to teach it to others.
