My mom, dad and sister have all done 23andMe, so it doesn't matter if I have or not. They have an entirely complete genome for me.

I agree with your limited license idea. It's just not ok that something like that can be dischargeable in bankruptcy. We don't have the ability to refuse consent in the first place, if our family provide it.

That's a lot of information, but it is in no sense a complete genome. It does mean that someone who had that information could prove that your DNA belonged to a child of your mom and dad with high accuracy, or that you were a sibling of your sister. It also reveals that you don't have certain mutations, or that you do have a few.

But where your parents have different SNPs, there's no way to derive which of them you inherited. What you said is a bit like saying that, because you know all of the cards in a deck of playing cards, you know what hand someone is holding, except in a counterfactual world where there are 10,000 possible cards and you know that a deck only has 52 of them.

When people describe DNA as PII, I don't think they imagine being involuntarily cloned (yet..), I think they're imagining heritable conditions becoming public information through data leaks.

People have a right to privacy from imprecise yet correct information about themselves. Someone wouldn't want to explain an abusive parent to a prospective employer, but they could see a strong tendency to, schizophrenia, with DNA data leaks.

How can they link your family's DNA to you if they don't have a profile or account for you? How do they know you exist? And if they know you exist, how do they know you are related to that particular family without some DNA information about you to link to them?

OSInt will happily fill in the rest. Even if you don’t have a social media footprint, your family does and they shoved their contact list, with you in it, to Facebook 10 years ago.
