How is this any better than a database?

It's not. This use case is pretty stupid since regulations make it impossible to allow true anonymous p2p trading.

Decentralized store and decentralized trust. The latter is hard with a publically accessible & editable mysql.

Except that this isn't decentralized - its a controlled blockchain that's only available for public download (which http does just fine) As does archive.org

I think you incorrectly understand how the blockchain can be updated.
