Well if their goal was to train an AI capable to be integrated in mobiles phones to be able to scan the eyes of people to unlock it, then it would have been a great goal.

Tho I am not sure of what they really want.

Maybe a a way to get data and sell that data later. They have the hash for the eyes of the people who got scanned. So in the future maybe they can sell that (or get hacked), and advertising companies could use that for tracking people with theit AI.

Maybe what they are trying is getting a lot of noise to increase the value of their crypto (no idea what crypto and identity have in common) and do a quick cash grab with people buying in it.

Maybe their real goal is making an ai capable to identify everyone and sell that ai as said above in security devices but not in advertising.

Who knows. But right now the way they are collecting the data, is pretty bad.

So, there's a lot of reasons we don't want our eye prints stolen.

One is causing it to be impossible for you to be anonymous in public.

And not for everyone else, just you - if you once looked at this art piece, and happen to partially match a demographic that someone decided needs to be tracked carefully.

Another is establishing a credit score for you based on your eyeprint which can never be cleared, since you can't change your eyeprint.

And of course, there's reliably being sure they assassinated the right person, by verifying the eyeprint of the corpse against their database of eye prints.

There's lots of profitable uses for stolen eyeprints, and none of them are nice.
