geographic location in internet means you are being tracked which is by definition part of what we want to stop. This is nothing like local advertising.
Local advertising is contextual advertising not personalised one. The equivalent of that in internet would be for example a Gardening website showing adds for gardening tools or a tech website showin ads for notebooks etc. these are tied to the context and are fine. the distinction is that when i go away from that context i'm not followed by those ads. Location based ads in internet follow you around no matter where you are. Imagine how creepy would be for you if you go to vacation in Hawai for example and see a billboard advertising for something in your home town on the other side of the world.
