Because your tracked data is still collected, psychologically and financially profiled, and sold and re-sold to other players.
So for example - once the banking system in Australia is fixed

and you apply for a mortgage but don't get one... your browsing profile might well have something to do with that.
Or, if you were US american and your health insurance suddenly ups your premium - it might well have to do with the fact that you subscribed to a Mount Everest fanpage on Facebook.
And so on. And that's only the effect on your personal economics. There's also the "benefit" for state agencies which can obtain the data pool and some stupid agent draws conclusions that make you a terrorist or something.
You as an individual are vulnerable in so many ways when your personal data is on sale.
