Actually, the real security flaw lurks in the warped minds of people who try to access other people's systems without their permission.
Ultimately, there are no technical solutions to the problem of human dishonesty.
It's exactly the same in the analogue world. You can barricade your house and add all sorts of barriers and bars. But while you have a way in, so too will the baddies. In the meantime, life behind bars becomes more and more cramped.
This problem will only get worse until we realise that the real solution lies in the values we have and the way they are instantiated in parenting, education, and social institutions. Morality and virtue requires formation. And until we tackle the problem at its root, things will just get grimmer and more unpleasant.
And all the rest of them ~ Brits, Germans, Russians, Chinese, French, Australians, etc, etc. At least they're less malevolent than the crooks who actually try to do real harm or steal your data for economic gain or just to wreck it.
