I think this is a tonic in contrast to the current hype, if a bit over-bitter. The larger problem that blockchain addresses, though, is, as quantdev alludes, is a way for actors outside of a firm to collaborate at scales previously only available to governments and (for some value of large) large firms.

In the parking car example, for instance, it is true that implementing a system to do that requires only RFID and servers. This means that at one time it was only plausible for Interstate System to use them, with the technology cheapening to the point that parking garage operators install them. Blockchain steps this down the next level allowing everyone using the system to also own the system.
