You don't even need a cryptographic signature if it goes to court. It helps, but not specifically required. Also, a court has no power to overturn a blockchain transaction - unless they have a bunch of miners and energy to rewrite the chain.

Some other differences include append only nature of blockchains. I don't know the ledger has not been modified or reordered or had entries removed. Also if the author doesn't like you, he could ignore your transactions or even drop the entry from the CSV. With say, Ethereum, you would be able to know all these things up front.
