Nice. I think this highlights how a hang-up on entropy estimation has a chilling effect. Sources that cannot be reliably estimated to provide "true randomness" are discounted and end up unused.
Entropy, like economics, is about counterfactuals, where what might have happened matters as much or more than what actually did happen.
Thus, estimating entropy is like making economic predictions. You discover that your Nobel prize winning economist is outperformed by a gipsy communing with demons.
If we think we need an accurate, rather than qualitative, estimate of entropy, maybe we need to rearrange our affairs so that a qualitative estimate will suffice.
