That's very different from what's meant by "reversible transactions" in the context of other payment systems. If the legal system can dictate the reversal of a cash transaction, then it can do so for a crypto transaction - without eithe…
Mine and everyone else's who holds important information in databases. The whole financial system for one.

Up to some size.
> Which is many orders of magnitude easier than the current system.
It is not. The current system scales with the number of home transactions. Your proposal scales with the number of homes - a much bigger number.

Sure, but then it's just a whole bunch of extra work for no benefits for 10-20 years. Not just for the county clerk, but also for home owners and buyers: not only will they still need to process the existing requirements, they would also have new requirements to obtain and prove ownership of their ETH/other crypto wallet. And they wouldn't see any advantage at all until the next time they sell their home (hopefully they will still remember their wallet address and private key by then!).
> On just about anything noteworthy that's not Ethereum, the cost is on the scale of cents. Wow, such unaffordable, many expensive.
Well, there are exactly two block chains that are somewhat noteworthy outside the crypto bubble: Bitcoin and Ethereum. And Bitocin doesn't support NFTs.
And any other block gain that becomes even mildly popular quickly explodes in values and transaction fees just like the other two. Turns out that storing hundreds of thousands of copies of the same data, and writing every single transaction to hundreds of thousands of systems before it is considered settled, without any kind of permission system, is actually very costly.
Note: you're right on the cash transaction statement, to some extent. There are still some important differences I feel, mainly related to the fact that today's systems enforce knowing the legal identity of parties to a transaction for something like a house, even if the sale is done in cash - which wouldn't be guaranteed if the house could be traded by selling an NFT on a chain.
