An ad-blocker for the physical world? Hmm..

Will employees of the city 'pop up' in your path as you walk down the street: "Hey! I see you're using an ad blocker! The city relies on advertisements to fund the street you're walking on right now, please consider turning it off!"

Your AR device will replace those employees with beautiful dancing girls, of course.
