A baby will become a powerful adult after 30 years, when their DNA info might become valuable (for forensic, health, research or other reasons). It's a long time for the investment to return. Why not sequence all people's DNA now, obligatory by law. All that it's needed is a little saliva and a wide lab infra.
While the people in power yesterday/today might not abuse databases of their entire population's DNA, those of today/tomorrow might. In the long-run, of 10y,20y, 50+y, you cannot guarantee this information will not be used for extreme harm. This is different that vaccines. Not everyone can be vaccinated, so to ensure that everyone is protected, everyone must be vaccinated. DNA sequencing at most only helps the person and at most their offspring. It should be a choice, and not mandatory.

out of curiosity, what country?
DNA info is not so much of value as it sounds. Genetic testing has very poor results and therapy is almost non existent. If they (govs and orgs) could extract value, they would make it mandatory for all, like fingerprint and face photo.
