I want a scaling license fee to apply (e.g. % pegged to revenue. This still has an indirect problem with different industries having different profit margins, but still seems the fairest).
And I want the world (or EU, then others to follow suit) to slowly reduce copyright to 0 years* after artists death if owned by a person, and 20-30 years max if owned by a corporation.
And I want the penalties for not declaring usage** / not paying fees, to be incredibly high for corporations... 50% gross (harder) / net (easier) profit margin for the year? Something that isn't a slap on the wrist and can't be wriggled out of quite so easily, and is actually an incentive not to steal in the first place.)
[*]or whatever society deems appropriate.
[**]Until auto-detection (for better or worse) gets good enough.
IMO that would allow personal use, encourages new entrants to market, encourages innovation, incentivises better behaviour from OpenAI et al.
