I.e. the fine print says “the key is the only proof of ownership” but the buzz says “digital wallet secured by spy movie tech”.

The point is A) buy low (at zero) and B) sell high.

Everything else is just a marketing ploy to get to B.

We'll introduce this idea that sounds really tech, and hype. Maybe imply its so difficult that computers could never compete with humans.

We'll say its about improving security, and most humans will get a vague comforting feeling from the idea that there's some security feature, even if they find it kind of annoying to interact with.

Five years later, we say "surprise, it was really about training an eyeball recognition database that we can sell. Just like the image recognition datasets."

I do not even kind of believe these people are dumb.
