To me, your example sounds more like a lifestyle choice, my friend.
My advice to the person in question would be to pull your head out of work and sample a little more of that big city while you're paying so much to be there.
There's no reason why every moment of time that isn't paid for by work to be spent on work, outside of that being a choice (given our current example, which sounds like a well-enough-to-do tech worker).
Personally, I couldn't live that way, and I'm probably filling out a few of your checkboxes above. I like the people I work with, but I value [and fear] time too much to give it all into my job—be it tasks, networking, socializing, whatever.
The example you extended sounds more like a problem of agency than one of [a lack of] leisure.
