If you are screening for something, the first test should have a low rate of false negatives. Anyone testing positive on that test should take a second--possibly more expensive--test with a low rate of false positives.

If you remove big blobs of flesh from yourself on the basis of a single test, you are not making your medical decisions wisely. The only decision you should be making on the basis of 23&Me results is whether to take another test that is more specifically targeted at the potential problem.

If 23&Me says you have BRCA, you don't get a double mastectomy. You talk to your doctor. You perform self-exams more often and more thoroughly. You get additional screenings that are not cost-effective for the general public with a lower risk profile. That's the whole point of consumer-grade genetic screening.

If I did see something that suggested a possibility of something, I would go the direction of what you mentioned in the last paragraph.

Although I agree with the FDA's actions, a consumer getting a thorough genetic exam is possibly what prompted this. Check out the artidcle http://www.bloomberg.com/news/2013-11-25/fda-tells-google-ba.... Turns out United Healthcare raised a concern which I believe is might be money-related. If your test results suggest a high possibility of some health issue from an non-FDA approved company and you requested a more accurate test, then I can see the health insurance companies getting involved.
