The cookie law was never well thought out, that's why nobody read it in the way it was "intended" (what was the intent anyway). The distinction between a regular cookie and a tracking cookie doesn't exist except in the minds of the EU regulators, so no surprise that all they achieved with this was making the EU web experience horrible by default instead of opt-in horrible - browsers have let you request notification of cookies being set since forever, after all, and you can create extensions to notify you in whatever way you like.
