@tek A take on this is Vermont does not allow billboards on the highways.
After being in Vermont and then driving to another state, the intrusiveness of ads becomes visceral.
I think of this even in the grocery store and they play basically ads on the in-store radio.
Once you see and hear the notion of intrusion into your mind you can't forget it.
I mean it's not ads but I also can't abide loud car exhaust for the same basic reasons. It's an "emotional" ad based on libertarian ideals.
