They can't ever work. You can't prove digital rights to a non digital asset. It doesn't matter what the blockchain says owns a property when the county courthouse says you do. They tried the same thing for "produce on the blockchain". "You can prove that this crate of apples was grown organic in Kenya". But all you can really prove is that someone put that claim on the blockchain and attached the hash to some paperwork. You are still trusting something and someone not on the blockchain. And how do you make sure this crate isn't swapped for another crate of apples that this isn't true for. You are trusting that no one did that during its transit. Blockchain can't work for anything that isn't a self-referencing currency. It only ever exists on chain so the chain can be trusted.
