Accelerating

In summary: Correct. You are using a family of clocks to establish a particular coordinate system to great precision....but then you can use that coordinate system to compare any two clocks without ambiguity.

Brian didn't seem to be presenting his method as "just one of several different possible answers" to the question of "What is the current age of the inertial person, according to the accelerating person?". My impression was that he seemed to present it as THE answer.

THE answer to what question?

If the question is "how can you do physics in a non-inertial frame" then it is not even an answer let alone THE answer. If the question is "what is the naive non-inertial simultaneity convention which most novices tend to adopt and which is useless for any actual physics" then I would agree that it is probably THE answer.

The concept of "no definite viewpoint" refers to the idea that, according to Einstein's theory of relativity, there is no absolute or objective frame of reference in the universe. This means that the perspective of an observer can greatly influence their perception of events, especially when it comes to the effects of acceleration on time and space.

For the accelerating traveler, this concept means that their perception of time and space will be different from that of a stationary observer. As the traveler accelerates, their frame of reference changes, causing time to appear to slow down and distances to appear to contract. This is known as time dilation and length contraction.
