Some people might ask what the point is. After all, you're still relying on a fair and enforceable court system at a base layer. That's true, but it allows you to abstract away all the other complexities from higher layers in the financial system. For example the cost of transferring title on land tends to be fairly high. You have stamp tax, title insurance, lawyers to review the contract, etc. With a DAO as the nominal owner, selling property simply becomes a matter of executing a smart contract transaction on the blockchain.
From there, you can imagine increasingly complex structures built entirely in the blockchain. A mortgage based smart contract can allow for a specific owner, but transfer the property to the creditor once the payment is missed. Mortgage underwriters can pool their blockchain based loans into pooled securities, and sell CDO-like products as smart contracts. This allows investors to completely bypass all the financial regulations and restrictions that exist on subprime mortgages.
It also cuts out an enormous amount of the legal, settlement, and due diligence costs associated with the creation of these securities. Everything's executed atomically and autonomously through smart contracts. The point is you can use a mix-and-match hybrid model, where some layers are secured through fiat law while other layers are secured through crypto law.
