That might matter in a niche case where the ownership of my moon share database entry is in dispute. (And each system has positives and negatives, blockchains aren't a strict upgrade.)

But the potential authority over the actual moon is the same under both systems.

Ownership only ever matters when there's a dispute. If you go build a house on a piece of land, and nobody ever comes along and disputes whether you own that land, does it matter whether you do or not? I mean, we even built into our laws that if you do that and nobody disputes it for long enough, then you get to officially own the land.

Right.

And a blockchain only solves a tiny percentage of ownership issues. It solves those issues with powerful mathematical certainty, and if you could live inside a blockchain your problems would be solved*, but don't confuse that sliver with the full set of real-world ownership issues that exist with or without a blockchain being involved.
