If an artist digitally releases a music album for free - it's worthless? Meaning it has no value? Let's break this down. If I construct a physical object and sell it - it has worth because you can hold it in your hands. If I record an album and release it digitally - it's worthless, despite costing me 100x more than the physical object I created. And despite you appreciating the music 100x more than my physical object. So what defines value? Then physical aspect only? I guess that's a theory, doesn't help to navigate the world increasingly dominated by intangible things, but okay.
