The "quiet part" that crypto builders won't say loudly about this is that they aren't trying to solve technical problems with real estate transactions. They're trying to make it so you can have real estate transactions with the authority being based on consensus of an unelected and unaccountable group of programmers/miners/validators running a blockchain, instead of the authority of a local government. The "problem" they have is really political in nature, not technical. At least, I cannot see any other reason why they would care about this when there seems to be even less interest in trying to deploy permissioned blockchains operated by governments.
