I think it does, because of its complexity, it's more of a set of technologies than just a software solution. Preventing double-spend is just the main use, however in order to do this a whole game-theoretical economic/technological system is required and that also solves and/or creates other problems. For cryptocurrencies, DAOs and similar systems economics is a security concern (wrong incentives will make it possible for an someone to game and/or break the system).

The point is that blockchains don't provide you with anything other than that "main use". For any other kind of feature you need to add something else - and if you're adding a centralized trusted authority (which is by far the easiest way to do anything), then you can get rid of the blockchain altogether.
