The blockchain is nothing more than a transaction record. It doesn't "enable" anything.
Bitcoin (and all blockchain tech) solves the Byzantine Generals Problem which is a classic problem of computer science. It means you can create distributed exchanges of virtual or real property in the face of people trying to lie, cheat, or steal. Its actually a pretty big achievement. There are distributed market places, distributed exchanges and other interesting developments in the works all based on the fact that we can now build software on top of blockchains. But please continue to tell us how Bitcoin doesn't enable anything and whatever DB table you (or your bank) use to store transactions is more secure than that.
