Especially given that you can download your genetic data from 23andme. I am not sure if Worldcoin allows you download a copy of your iris data... no mention in their FAQ, at least.

But they provide so little information compared to the DNA you provide. You get stuff like "ancestry" signals which americans love in their quest for racial validation, but they get to connect humans to a point they can find the family of an unknown murderer whose DNA was found on a crime scene.

Which information is more precious overall, which is a call to action rather than a simple joke between friends "oh im 3% Banana".
