Being laughed at doesn't seem to stop people from trying to solve problems by throwing more blockchain at it.

From my PoV blockchain can be the solution for a lot of things, but is not suited for most of these problems. It is "just" a technology like any other, but with a focus on trust in decentralized systems. If you need this then blockchain could be a good solution, but this does not mean that it fit your needs in transaction speed etc.
