I think you've proven the point. Exchanging keys on a bike forum first or chess club means discovery is happening on external forums, not on Pubky. That's outsourcing the difficult part of the problem...
The external forums [venues] are indeed an onramp, and means to establish the first few peers [followers/friends].
But thereafter, a Nexus server isn't required in order for users to expand their network, and crawl results [index files] can be stored locally.
Relays/intermediaries are not foundational to bidirectional communication on Pubky, because peers can push and pull data directly between one another.
Coupled with Kademlia (see: PKARR) this confers true decentralised mesh properties.
Nostr exists inside an airlock, and uses authorities to relay data.
