It's not really looking like that's an option too many folks care about anyway, given the survey results so far. As for the concerns: 1) The original audio did mention that there would be difficulties on the hardware side of that fence - leasing a car may have been a poor example, but it was just an idea of one kind of transaction a "smart property" system would be capable of. 2) There is actually one big benefit of adding Bitcoin to that mix: You gain the benefits of a publicly published block chain that's not reliant on any centralized source as is the case with traditional key signing. A bank could implement this for their loans right now, but it would be reliant on some centralized source to enforce the payment schema. With the bank as that source it would be a very lop-sided relationship with one central point of failure. With the Bitcoin protocol as the source of contract enforcement the balance of power between you and the bank is even and your single point of failure is now a distributed transaction network with tens of thousands of nodes.
