In the case of artists the foundation of the trust relies on the fact that the token is only valuable if it comes from the artist. This doesn't involve locking anyone up, as tokens created by people who aren't the artists are simply ignored since they inherently have no value. There's no reason to assume that in other domains what you said should be the case more often than what I said if we both don't know the details of said domains.
