What is to happen if a land-owner drops their cell-phone with their private keys, and now needs to re-gain ownership of their land? Well, either the government/admins can update the blockchain to have a new private key as an owner (in which case they could be bribed to do the same), OR the blockchain will be inaccurate, it will have an old address owning some land even though no one can use that address. See also, a farmer dies and has no beneficiary.
Also, how is new land added to the blockchain and old land removed? If the government needs to exercise eminent domain to build a railway, the farm's boundaries are changed. Perhaps the farmer does not want to make the update... so how does the land get updated to align with reality?
Natural disasters can also make land change drastically.

This just seems bad. Easier access to credit has not been great.

They are if you have a lot of nodes. Which you do if you use bitcoin/eth/whatever (but then the cost of doing anything is incredibly expensive for those in the global south, so it's unusable). If each town builds their own to manage their land, it would be just as replicated as a .json file in s3 people can mirror if they want, which is to say archive.org might save a copy, a few farmers and companies in the area might, but most people would not care. Heck, people mirroring a json dump of a database would be more likely to happen than people figuring out how to spin up weird blockchain software I bet.
