If it were intrinsically valuable then it would still be valuable if you took away the businesses. Would your healthcare software be valuable if there was nobody to produce the video course? Would your youth group be valuable if nobody attended it? What are you empowering the youth to do? Also write software to empower the next generation? It has to end somewhere.
You can't eat software. You can't eat gold either, but if society collapsed I bet you'd still be able to trade a gold ingot for a carrot, because it maintains a modicum of value. I doubt you'd have many takers for a JPEG codec you just wrote, though, and that's far more generally useful software than business software which is what most software is.
