A superb rant. I confess I am quite productivity orientated when being creative, but I do relax when reading books, watching TV, going to the cinema, etc. And yes - I often sit (or slouch) in silent contemplation, or do the same on walks in solitude. My mind is a fascinating place to disappear into, and I am never bored.

Also, regarding workaholics, or side hustlers (ghastly term) or whatever... No one ever lay on their death beds wishing they'd spent more time working.
