The notice is only for cookies used for non-essential tasks (like analytics) and doesn't have to be shown for things like login sessions. Your browser can't distinguish between those.
Prior to that you could just disable them if you liked.
One can say that policy makers had good intentions - certainly. However, I can not imagine a valid evaluation that wouldn't conclude this policy as failure.
The browser not being able to distinguish between essential and non-essential cookies does not change the fact that cookies are and were entirely voluntary.
