I disagree, why can’t land ownership be in sealed documents much like court documents can be sealed? It’s still registered as before but the documents are available to just anyone anytime without reason and they stay out of the clutches of the sleazy data dealers and such that get my address this way and send me junk and harass me in other ways.
Obfuscation past this would still be possible as you said but the default should be privacy to the owner.
