So if there are genetic roundups, why wouldn't they be accompanied by compulsory testing?

It's pretty much the same story with milder stuff like insurance. If companies can make money by offering discounts for people with genes they like, the insurance company not having your DNA isn't going to make your insurance any cheaper. Or employment, enough people will share their DNA that it becomes a necessary step towards getting the job.

The consequences all flow from allowing society to become hell, not from sharing the DNA.

Because one requires instating mass testing while another requires just gaining permission to an existing treasure trove, albiet a subset.
