Do you think a bearer asset like cash has zero use cases? Bitcoin allows settlement much like this with a party that doesn't need to be identified and already trusted by a central clearing house. Of course this can be dangerous and might not be desirable for every transaction, but there clearly a technological achievement to make it possible.
Proposing opening an LLC is a pretty involved workaround that again requires more supervision and gatekeeping (e.g, for many people and many countries this is not even possible). Cash like settlement with any person on the planet without any intermediary is a pretty big technical achievement that absolutely was not possible before blockchain.
