Using cryptotokens as a method of recording who-owns-X-physical-thing seems useful at first glance. It would work for as long as there are no bad actors. The main issue is dealing with a 'fork'. If Person A has the private key that 'possesses' an item, but the courts say that Person B is the rightful owner (and physically transfers it to them), how do you securely fix the chain? If person A cannot or will not be compelled to transfer the cryptoasset with their private key, then the chain now has incorrect and uncorrectable information on it. If some records on your chain are not trustworthy, trust in the whole chain breaks down. The only fix is requiring a centralized backdoor, at which point you might as well just use a non-blockchain database.
