>What would the pros/cons be if we did the opposite, if everyone at birth had a DNA swab taken and recorded.
Then I'd have my baby at home with a midwife.
>Apply strict rules about individual viewing access for criminality only with clear logs and then it was open at some anonymised / grouped level for research.
Like the strict rules we have here in the United States preventing the CIA, the FBI and the NSA capturing and sifting through the communications of US citizens? Rules that are routinely violated and ignored with no criminal penalties or sanctions ever handed out?

>It kind of feels wrong but why?
Because if history has proven anything, it is that people in power are above the law. They can not and should not be trusted with our genetic information.
>Are the risks focused around bad implementation of the system and/or slippery slope type arguments?
No, rather the total opposite. In every single case where information is available to the government and/or those in power, that information has been accessed, shared and data mined, without exception, without regard to the law and without any legal sanction to those who break the law by illegally accessing this information. From, "parallel construction" to the Snowden revelations to the recent abuses cited by Senator Wyden, only willful ignorance can possibly allow anyone to trust the government and the powerful to follow the law.
