The schemes that I'm aware of mostly have huge side-channels in the proof. I think I constructed one before that didn't have one for proving bilinear keys, and it only proved a pubkey was a pubkey, but at best it's an extra constraint. Goes back to what you're trying to accomplish, like assume network capacity to process/forward blocks as a fixed amount. Your concern with NFTs is them driving up fees. So now every transaction has to carry a proof its not embedding a jpeg and so the effective throughput of the network is halved or reduced by 30% or whatever from the proofs. Not a win. And of course were then imagining something with more cryptographic complexity than the whole of bitcoin just to close high bandwidth channels. And low bandwidth channels on the order of 24 to 32-bits per independently adjustable piece of data still exist. But Amazon doesn't offer a service to store data on S3 forever. It doesn't my example was an economic analysis that just assumed you bought an investment to yield enough to pay for the S3. If you actually want it you can construct it as a legal entity. Also of course, S3 only offers storage. Not publication. Things like Citrea (and Lightning) specifically need data publication. Right I might have been unclear. Some people are laboring under a mistaken belief that the objective of people putting large amounts of data in the blockchain is just to "store stuff" --- and my point is that it's outrageously uneconomical for that. While there may be some on the margin, the reality is that people storing something believe they're getting some benefit out of doing it that they don't get from an actual storage solution.
