The larger point is that industrial civilization (or post-industrial) is probably at a point where you can feed, clothe, and shelter every human being on the planet, but our moribund systems do not permit it to. Hence the rise of critiques such as Graeber's Bullshit Jobs, and the rise of alternate proposals such as UBI, federal job guarantees, even revival in interest in land value tax. As William Gibson said, "The future is already here – it's just not evenly distributed."

We probably could support a system where we have a creative class of people doing hobbies all day- after all, we did in past-industrial epochs with wealthy aristocratic patrons and so forth. But we don't because there's not sufficient incentive to build that world, yet. In the meantime we get a lot of corporate make-work and capital being thrown away at enterprises that probably don't actually create lasting value.

So what I'm getting at that what you deride as profitless passion is low value because of entirely arbitrary reasons. There's a ton of bad enterprise software out there, to pick one thing that's monetarily highly-valued, yet they don't seem to provide humanity with lasting value.
