Agreed.

I see it via a "set theory" lens.

Like, the subset of quadrilaterals that are rectangles contains the subset of quadrilaterals that are squares.

Similarly, the set of people who are lonely because they have no one with whom they can communicate things that seem important contains the set of people who are lonely because they literally have no people around them.

Basically Jung was saying "Hey...the green bullseye is still a bullseye in the lonely game...it's not just the red that counts."
