Some people putting and infinitely reproducible digital commodity (song, audiobook, pdf, podcast) and expecting their audience to pay for it are practicing v4v. I would argue they're actually practicing a form of Marxism. Maybe I'm wrong in my assessment of what it is they're saying, but it sounds a whole lot like "Labor is the fundamental source of economic value." There seems to be this idea that "I made an album or podcast, and my listeners should support me." Maybe... if what you're providing is valuable enough to them. 

Maybe giving some of their very precious time to understand your ideas is all the value they derive from your work. Maybe it's no more valuable than that to them, and they owe you nothing else. They've already given you their most precious resource, which is their time. Anything else is icing.

If I was to make a mud pie and an apple pie, I could've spent the same amount of time and energy creating both. It could be the most impressive mud pie in the world, the best ever created. I could've spent hours crafting it, many more hours than I spent on my apple pie. I can value my time at $50/hr, and spent 4 hours on this pie, and say it's worth $200. But that doesn't mean the mud pie is more valuable than the apple pie. Only you, the consumer gets to decide it's actual value. Only you get to decide if that mud pie is worth $200, or $2, or nothing. 

So what do we do with infinitely reproducible digital commodities that I build once and put out in the world. I give it away for free. I expect nothing in return and I ask people to pay me what they think it's worth, which may just be a listen and nothing more. And I hone my craft to a point that people want what it is I'm building, and would be sad to see me stop creating, and are willing to pay me to continue doing what it is I'm doing because they value my creations. My creations enrich their lives in a way that their day would be less bright if I wasn't creating, they love being part of the community I'm part of and want to grow that community, so they contribute their time, talent, and treasure. 

v4v requires faith. Faith that want I'm building is valuable (and for me, my creations are like the Velveteen rabbit. They're real because I love them, it doesn't matter if someone else does, ultimately, they're for me and my enjoyment, your enjoyment is icing), and faith that you'll value what it is I'm putting in the world enough to freely give me some of your very precious time, talent, and treasure. v4v is not for the faint of heart, it's for those with a tremendous amount of faith and courage.
