This is probably the most coherent take I've seen on this - there's no logical reason it should be generally appealing or even seen as correct (it's basically a pure anti-change position) but it's one that has consistency and makes logical sense, even if you say "Well that's codswallop!", which I don't think is true of even one single other TN take I've ever seen (I have seen ones that seemed to be roughly pawing at this sort of idea, but never quite grasping it).Well, the utilitarian answer is ask your DM as they're the only one that can answer that for the game you are in (and perhaps not even then).
IMC (or at least most of them), True Neutral would seek to limit the effects of the outer planes. The prime material is not good or evil, lawful or chaotic, it is a mixture of all of them. Every world in the Prime Material works at least a little bit differently than the others and each has its own spiritual component and afterlife that matches the make up of the physical part of the world. The outer planes operate by different rules and can be considered pure Good or pure Evil; Law or Chaos. Both are not meant to be in the Prime Material and contradict the Natural Order no matter where they are in it. Thus, the True Neutral are those that seek to limit the effects of all of them.
Somewhere I have a scene written up of an angel meeting a good adventurer. It describes how it come from a plane where there is no death, suffering, war, or selfishness. It looks upon the adventurer with revulsion as its body is a churning charnel house of the things it considers Evil. There is birth and life, but it is locked in an eternal conflict of kill or be killed where animals and plants much be murdered to sustain life. Even inside of it, the bits that make up its body are at war with intruders and even deviant parts of itself. Still, it smiles as it knows the adventurer means good and seeks to be what it can never be. So it will help. However, it needs to do so as quickly as possible. Its very nature attacks the natural order. It can feel creatures to small to be seen land on it's body and failing to find anything that can sustain them begin to starve, suffer, and die. It's every step crushes living things under its foot. Even when its energies interact and bring forth new life to replace what was killed in their footsteps, of these new plants and creatures most will not survive as they are not meant for this world. Of the ones that do, they will just enter into the cycle of life and death, thus the angel contributes to the system it finds so repugnant. It is also meant to be an explanation of why the higher planes do not walk the prime material as much as the lower planes creatures who find pleasure in the suffering, death, and corruption they cause by just existing where they shouldn't.
This would be a good take a Druid-type TN particularly.
What undermines it is that the G-aligned planes actually do have a lot of killing and eating and so on, but with different Good planes where that wasn't true (which there are plenty of in mythology), it would work.
