"Cost savings" is never a valid reason to use blockchain technology. It is and always will be inherently more expensive than running a normal database.
The only reason that users might be willing to eat that cost is if they believe they are "owning" an asset that will appreciate somehow (a la Cryptokitties). The second the thing they own stops appreciating, they stop paying to play.
