the wonderful brightness brilliance of the guitar

Agreed, that's going on my playlist.

It may be a demonstration of skill. There may be easier or other ways. She is tapping with her right hand fingers, not picking. Each tap gives the note at that fret. Although she may tap, pull off or pluck the string depending which note she wants combined with the relevant finger positioning on the left hand.

Another thing is that she only uses the plectrum whereas she could use thumb and fingers if she or someone else chose.

For economy of movement the electric guitar is actually better, even with plectrum only.

Take a simple downward three note progression on the high E string, A,G,F. This can be done with only the left hand in three movements.
With left hand in place, pinky over A, 2nd finger on G and 1st on F#.
Hammer pinky on A gives you A
Pull pinky off A gives you G
Pull 2nd finger off G gives you F#.

With traditional classic style it takes 5 movements.
3 (rapid) picks with right ring finger.
And lifting 2 fingers of left hand.

So all is not what it seems.
E&OE.
