So you persist is saying that D E A is a different chord than is D A E. Your reason is that the sus2 requires the close interval. I and others have asserted that the voicing doesn't change the name of the chord, (at least without context)*. That's why I suggested that your logic would preclude calling D A C F# a D7 because it's not the same as D F# A C.

No, my logic wouldn't suggest that at all.
* The notes D F# A B could be, depending on context, two different chords- either D6 or Bmin7. Now if it's just these four notes in this order without context I'd say it's D6, but if it was played just before an E7 or the bassist played a B, I'd certainly call it Bmin7 even if the guitar or piano voiced it D F# A B. Context is vital.
Yes, I do NOT disagree with that.
An
Ab Augmented Sixth Chord (i.e., Ab, C, Eb, F#) sounds the same, on it's own, as an
Ab Dominant Seventh (i.e., Ab, C, Eb, Gb), but they do NOT function the same. Context is vital.
For instance and within context, as you've pointed out, a D6 (D, F#, A, B) is NOT the same as a Bm7 (B, D, F#, A) even if the Bm7 is in first inversion (D, F#, A, B).
Sure, on their own and without context, Bm7/D
could sound identical to a B6.
I think there is not a thorough understanding of "Added Note" chords and "Suspended" chords and their differences in this post.
"Added Note" chords do not need to necessarily resolve AND contain the Third.
A few examples:
C add 2 - ex: C, D, E, G or C, D, Eb, G
C add 6 - ex: C, E, G, A or C, Eb, G, A
C add 9 - ex: C, E, G, D or C, Eb, G, D
C add 6/9 - ex: C, E, G, A, D or C, Eb, G, A, D
I have seen different labels used for these chords by not using "add", such as C6/9 or C6
Then there are "Suspended" chords. In the "Suspended" chord, the note that is being suspended
usually is followed with a resolution to the Third (major or minor) of the chord.
sus2 - ex: C, D, G resolves to either C, E, G or C, Eb, G
sus4 - ex: C, F, G resolves to either C, E, G or C, Eb, G
This is why the OP's chord of question is a
D add 9 (no 3rd), since the vital context is excluded or does not exist and the pitches are spaced Perfect Fifths apart.
That's the logic.

Additionally, there are "Suspended Slash" chords - such as C/D (C, E, G with D in the bass). These could be relabeled X9sus4 or X11. This is a whole other subject.
