Practically speaking, who is going to enforce such a regime? Do you really want to give Chinese companies such a huge competitive advantage, that they aren't subject to the same costs as western companies? How do you even sort out which "creators" are owed, and how much? It's next to impossible, and would drown the legal system in litigation; it would likely cause more problems than it solves. On top of which you can find open weights for most, if not all, of the scraped material already. If you make those illegal to use, or prohibitively expensive, you just destroyed local LLM legality, and put the technology firmly in the hands of only the monopolists.

If models are trained on the collective whole, they must be owned by the collective whole. If you believe funding creators for the training of private models is too slow, inconvenient, or creates a global disadvantage, then embrace collective ownership.
