There's a very simplistic "in principle" reason to consider the blockchain. It can store information symmetrically - i.e. once you have access to it you have complete ability to search it and reuse the data, and it can't be "lost" like data you've stored on a server or a hard drive - it only goes down if the whole network does. This maximizes information availability and reduces the middleman problem to "who provides hardware and bandwidth" and "what ui is available for accessing the blockchain." Although bitcoin makes the blockchain look capitalist, its underlying tendencies are like that of the internet at large - self organizing infrastructure for information.
