So actual data that proves that this physical person is the owner of this physical asset.

Ah yes. Because when it's stored in a non-centralised database of "local computer at owner's residence" or "hosted server controlled by the owner" that data is easily accessible and retrievable.

You can replicate it to multiple sources or use a decentralized storage solution if you are concerned about data availability.

Who is this "you" who is going to do that?

Remember we were talking about property deeds? Their availability is of great concern.

Before you answer that, go back over all your comments here and in other threads, collect all the limitations you've run into, all the workarounds you proposed, all the additional external systems you need to run just the most trivial of scenarios, and riddle me this: why would anyone want this?
