Which never happens nor is their any sort of guarantee the government will actually give up such information.
What are you talking about?
23andMe is a commercial entity. I have no idea if any minors have in fact requested their accounts be deleted, I assume they will honor their policies.
Some governments do, in fact, have DNA statutes that require the DNA of innocent individuals to be purged from their databases. There is absolutely no reason we cannot pass such laws as we see fit -- or laws that bar police from acquiring DNA without a warrant prior to conviction.
We also do, in fact, have examples of changes in statutes when a SCOTUS ruling rubs people the wrong way. For example,
Kelo v London extended the powers of eminent domain to private developments that, in the view of local officials, met a "public use." Since then, most states have passed laws that drastically restrict exactly those types of uses of eminent domain, in direct reaction to both the ruling and public outcry.
So if you
really think this ruling is wrong, it is entirely within your power to change it. That's the great thing about a representative democracy, by the way.
Btw, you of course have ownership towards your own body, just like the child owns theirs. It can be no other other way.
It can and it must, because your status as a person, rights to privacy, and protections from certain government actions are not grounded in property rights.
Of course, all you listen to is the government, so talking to you is like screaming at cement and demanding it to not dry.
No, I'm merely using the law as a convenient reference point. It's a codification and formalization of how we handle rights.
And more importantly, you fail to realize that in many cases the government has to listen to
us. We're the ones who decide who goes into office, and we are the who push our legislators to pass or repeal laws.
