Nostr is quite open for what options people use to become more trustable. People can pay couple thousand sats to get a verification, or as you say Nostr can also do the same with shifting to web of existing sources of identity.
E.g. it is well known that this Jack is CEO of Strike (strike.me) and so any nostr client can verify that https://snort.social/p/jack@strike.me is trustable, because it serves his public key here: https://strike.me/.well-known/nostr.json
