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.
