If home ownership was on a distributed blockchain, local regulators would rapidly discover a need for something like a notary to verify that the transaction has been done correctly on the correct blockchain by the people who actually own it, so as to ensure the consumer isn't sitting on the other side of the table with someone not bamboozling them about their ownership of the house, or bamboozling them about their transfer of ownership, or so and so forth. The notary would also validate that the transfer has successfully been completed on the blockchain respected by the local governing authorities, and has been filled out completely correctly.

You might think this is silly, but fake selling of homes is actually thing that happens! I don't just mean that regulators would do it for gatekeeping purposes, I mean there would be a real need for this. In the bizarre circumstance that this move to the blockchain actually happened for home ownership, the HN gestalt would rapidly be screaming for legislation and regulation around blockchain changes.

Which means, once again, that blockchain is solving a problem that doesn't exist here. The problem with home ownership and the problem notaries are solving was never that the authority was too centralized into the relevant governing bodies.

That's the reason why after 11 years blockchain has exactly one use case, and even that one is dubiously solved IMHO. It brilliantly solves problems we don't actually have.
