It's one of those "single-use-case" coins... which already limits what it can become.
And here the use-case doesn't even make much sense. Why would a land registry need a blockchain? Blockchains can't be freely edited - land registries need to be. You need a central authority to verify ownership. And all the remaining problems can be solved with an open database.  
People seem to forget: Blockchains are not efficient. They are super wasteful. They just solve a very specific problem - one that doesn't apply here.
