It is impossible to have an "expectation of privacy" over the DNA of your relatives. You need to live with it, and resolve your feelings to the reality of that situation.

You don't get a choice if your uncle, grandmother, aunt, niece or son share their DNA with law enforcement.

I'm not sure it's just feelings to be resolved. The problem is that even DNA matching, especially the SNP genotyping which tends to be used by consumer ancestry and heritage services, is not perfect. So your daughter can end up false-positively matching to a crime 20 years from now due to your uncle submitting his own DNA last year without you ever knowing. I'm not sure how anyone sufficiently familiar with the implications can just get over it and accept the reality of the situation. It is by no means an easy problem to solve.

That’s very true but it’s more of a criminal justice problem than a privacy problem. The same issue could happen (and has) with fingerprints or other biometric data.
