The ownership economy thesis is that value in past web platforms — Wikipedia, YouTube, Twitter, Peer-to-peer networks/marketplaces, etc — is generated by users who never retain any of it. Users contribute value, but they don’t capture it.
The whole music industry is something like $20B. Compare it to video games, a $140B market, and you see the discrepancy. Fortnite alone makes $3B a year, and most of it is profit. Same with League of Legends — they make $2B a year, mainly selling virtual goods.
Many issues people have with social networks and technology arise from a mismatch between the nature of these networks and the legacy corporate structures that govern them.
Music has just as much engagement as video games; there’s basically no reason there should be a 7x difference in market size — except for the business model.
The best business model pre-internet was to charge for content. In the internet age, I think the rest of the world will become more like video games — give away the base layer, and let the internet do its thing, supercharging viral marketing to monetize the complement.
