Your second sentence doesn't wholly align with your first.
Exclusively storing any data set in a single location is a bad idea, yes. But that's not an argument against a centralised register of all land ownership. My property is registered with the Land Registry but I keep a copy of the documents and my solicitor keeps the same in their files.
You’re right, that was an illogical argument. However, it’s important to recognise that the Land Registry as it exists isn’t just a public copy of the data (useful for research, public policy etc.) - it’s the single source of truth about land ownership. Once your land is registered, ownership disputes operate differently, whether you’re holding the deeds or not.
And I am not a lawyer btw so take all this with a pinch of salt :)
