And it's ALWAYS the same problem. You can have all the lists you want. A central authority has to recognize and enforce that list. At which point, the structure of your list is completely irrelevant. It could be ANY list. What matters is that it's chosen to be enforced. And currently, most power structures are happy with plain old databases. Or pen and paper.
A plain old database also has ways of dealing with theft.
If someone steals your crypto keys and sends your assets to themselves, they have no legal ownership over those assets but they're listed as the owner in the blockchain, so blockchain isn't even any good at being an accurate, verifiable record of ownership.
Yes, you can't make changes to the blockchain, but that also means you can never fix anything. So you actually can't rely on the blockchain to be accurate.
