I think there's a fundamental difference between "speculation backed by speculation" and "speculation backed by feedback from some high-quality signal (ideally, reality itself) on reasonably short time periods". Ponzis are the former, and if you make something that is the former, then yeah, it's a ponzi. If you make something that is the latter, then to a first approximation, you have some hope of instead getting the benefits of a stock market. What I'm advocating is more like "ISAs for creators" than it is like creator coins as they have been done so far. The ultimate buyer that backs the mechanism is NOT greater fool theory of even more token buyers, rather it's creator DAOs collective-bargaining for other forms of revenue (eg. they could make their own subscription platform, or they could organize in-person events, etc etc)
