> this fingerprint is on Crunk's profile to basically tell the world that this is real Crunk's profile, correct?

No, this is like an address where to send encrypted things, claiming that a key is Crunks is still a matter of trust, and people the import the key would still need to trust the key.

A signed post could use the keypair reference here, so you could prove that the signed msg came from a specific key, but again, trusting that a key is authentic is homework left up to the user.
