You might think that but I couldn't possibly comment.
I believe that Tesco has the biggest database of personal information in the UK, but they don't share, so far as I know, it because they get competitive advantage from it. Experian and Equifax also hold large amounts of information about us, but no one seems to care, about that.
Bust share medical records across the NHS, which might actually save your life, ooh can't have that.
We expect the government to know all sorts of things about other people so that they can prevent child abuse, benefit fraud, and so on, we all want the government ot stop these things and hold data on all those nasty anti-social people, but not on us, oh no.
Be real, to catch bad guys you need information on good guys as well, a lot of the current methods of catching bad guys depends on the ability of the investigators to detect aberrant behaviour. Before computing a lot of this was detected socially, by individuals, but know a lot of our lives go on on cyberspace hidden by pseudonyms and obfuscation, that can only be detected by knowing stuff about everybody. BTW this also works for a surprisingly large set of other more benign applications in health, finance and government making life better for you.
I can think of one country where everything is centralised, and citizens get excellent service delivery, sadly, it's also a despot. At least we can argue about it, not like their citizens, but we have to put up with disparity of service delivery.
