Maybe. I think that satisfying work (stressing that it's "work" not just pleasurable activity) will always be creating value. And value is valuable to someone, in some way, hence there's a way to make money from it. Maybe not very much money... A second problem is it might take time before that value is recognised. Hence, the painter's, actor's "day-job". Passive income is a day job. However, it's actually quite difficult to find a passive income niche, it's work and risk to do it, they usually end up not being 100% passive after all, and few niches are stable long-term (even huge enterprises don't last forever).
