> And still not a single example of a good real world use case

"real world use case" is in the eye of the beholder.

My grandmother never wanted a telephone (landline) and never understood the "real world use case" however much people told her they couldn't live without it.

She was not stupid in any ways I can think of. She just lived in a way that made the device uninteresting.

In any case, you should take a look at the gaming space.

Lots of movement around unique items, characters, or more generally control of virtual property and managing them through a blockchain so as to allow use across gaming platforms.

But that's not a "real world use case" after all, it's just gaming (a tiny, $90B industry).
