And to the horror of most crypto-currencies enthusiasts, blockchain will likely end up being used as a tool just like SQL servers and distributed clusters, by large companies and governments instead of being the instrument of challenge to these established entities.

This progression already seems to be occurring. Recently the CEO of JP Morgan even derided Bitcoin as a scam, while JP Morgan promotes its own internally-developed blockchain Quorum.

Now why would a major financial entity want you to think external decentralized technologies are scams, and their in-house solution is fine and legitimate and secure.

Property title, availability of airspace, really any complex system that requires mutual cooperation (or at least awareness) could benefit from uniform distributed ledger technology.

How would blockchains help with property title management?

During the subprime crisis there were reports of loans which had been flipped so many times that the chain of title could not be determined.

A blockchain is needed to solve this problem though.

For a comprehensive answer see Avi Spielman's thesis, in "Blockchain: Digitally Rebuilding the Real Estate Industry"

"The research to date leads to the following conclusions: A blockchain title recording system is the future of title record keeping and would provide immediate benefits over the current title recording system, with additional benefits accruing in the future as blockchain technology grows in acceptance. However, at the moment, these benefits do not yet outweigh the costs and challenges associated with implementing a prototype blockchain title registry system in Davidson County, or elsewhere in the country. That being said, steps can, and should be taken now to lay the foundation for a blockchain system."

I can't find an explanation in your excerpt nor in the paper that gives specific details as to how the blockchain is uniquely beneficial for property title management. I see some examples of how certain qualities of the blockchain could be beneficial, (e.g. property owners being identified by a private key), but you don't need a blockchain to get any of those benefits.

Aren't these already solved though?

can you link any property title stuff? do you mean commercial residential or both?

Sorry just seeing this now. Both, actually.

Avi Spielman, in "Blockchain: Digitally Rebuilding the Real Estate Industry" does a terrific job addressing and exploring "aspect(s)- recording property titles- by comparing the benefits and limitations of a blockchain with those of the current record keeping system."
