I'm saying that a cryptocurrency doesn't need to be permissionless to be decentralized. we can build a web of trust concept.
Permissionlessness is exactly the point though. Decentralization is only a means to an end.
Simply put, Bitcoin is not permissionless so that it can be decentralized. Bitcoin is decentralized because that's the only way for it to be permissionless.
Decentralization is the easy part, it's permissionlessness that's the tricky one.
