Certainly it can be used as a record of ownership. But it's not the real record - that's whatever the legal system holds. So now we're talking about just using it as a view on top of the actual system of record. It being difficult to mess up doesn't even matter, because it's just a view - it it's wrong go back to the source and fix it. Distributed consensus doesn't matter, because no matter what the consensus says the truth is whatever is in the legal system. The main design goals of a blockchain are valuable for a system of record. They are not valuable for things that are just a copy of something else. So while you could use it for that, it's not a good fit.
