I think restoring copyright to sane periods is a better solution, resale of digital goods requires online DRM systems to continue functioning indefinitely and we’ve seen the issues that causes.
I would be less annoyed by essentially consumable digital goods if I knew sometime down the road they would enter the public domain in a reasonable timeframe, and not well after the eventual death of the current generation of children.
I shudder to say this, but that might actually be a use case for blockchain. A shared distributed ledger that an ebook reader consults before opening an ebook.
