You do not need a banner, you need informed consent. I'm sure there are other ways of getting consent other than a half screen pop-up with a big red accept button on first visit, but they probably won't get 70% "opt in" rate.

Law: The optimum behaviour is annoying banners.

Companies: Annoying banners.

Legislators: Mission Accomplished. A win for the good guys!

Situation persists for at least a decade.

A more accurate version:

Law: You have to get some form of affirmative consent if you want to do specific often-abused things.

Companies: We'll do it in the most obnoxious way possible ("here are our 853 technology partners... no, there's not a 'deselect all' option, have fun clicking") so people blame the law instead of the industry that didn't want to allow consent at all.
