This is a conclusion I came to in 2017 and have been trying to solve it since.

Unfortunately I don't have the expertise to implement a protocol that would decentralise reputation. What Bitcoiners don't want to talk about it is reputation and trust are two sides of the same coin, and storing reputation data anywhere is fraught with risk and potential abuse.

My instinct is that trust has to start from hyperlocal networks below the Dunbar number, consider them tribes, which themselves have reputation and membership confers on a person the status of the tribe onto the member. Maybe you could have even smaller networks inside tribes called "families" or "projects", and then above twice tribes "communities" and "societies".

Reputation can be governed by an algorithm modelled on Pagerank with different weighted endorsements, on a scale from implicit to explicit, or increasingly costly, e.g. follow = implicit endorsement; donation = explicit endorsement.

Maybe something like this can be built onto Nostr, where there is a concept of continuity of identity that is unlike bitcoin.

Either way it needs to be built out of a system that aggregates real world event data.
