Appreciate your feedback.

I don't think it's accurate to say that we haven't come up with anything. The original Freenet has had a decentralized web-of-trust plugin for over 20 years[0].

It's far from perfect, in practice it seems to have empowered a small number of people with disproportionate influence - but that's due to solvable design issues, it's not a sybil problem.

It's also important to distinguish between sybil-proof and "raising the cost of sybil attacks to the point that they're manageable".

I do agree with your broader point that there is massive scope for building truly decentralized governance systems on Freenet. I've done some thinking about it but it's still very speculative[1].
