A permanent ownership record that exists beyond and outside a company

 The photos I take, the movies I buy, the music I rent, the emails I write and receive, the messages I send - all of these are captive. They exist within a database controlled by Google, Netflix, Spotify, Gmail, WhatsApp. If these services disappear, so does my ownership/rentership record. In a future where digital assets are worth not $10 or $20, but hundreds or thousands of dollars, ownership that survives a company becomes an essential substrate of commerce.
