I go back and forth between feeling this way, but I've taken the plunge and I have two of these "cash-flow muses" in progress. They've both had sales, and one is close to being profitable.
Here's a couple of other thoughts:
1. Hackers often dramatically under-estimate the knowledge that they have...something that's easy for most of us is probably near impossible for 99.9% of the population, or at least they think it is.
2. For me, I don't view this as something that I'll dedicate any more time or energy to than is necessary to free my time. The whole point of a muse is passive income to allow you to pursue whatever you're really passionate about.
