Are you one of the same people that refuses to pay for any content on the internet too?
That's a bit of a strawman but it also beside the point: advertising is by definition wasteful. I have for years ignored all kinds of adverts especially for things like cars, which I've never owned. I'm not alone in this and this behaviour is factored into the model.
The solution isn't better targeting, it's better ads and particularly ones that don't disturb the flow. The targetting is a red herring pushed by media companies hoping that advertisers won't demand lower rates once they realise things are just as inefficient as they always were. This is one of the reasons why Instagram is doing so much better than Facebook's own ad networs, because, given a choice most sellers would prefer to be able to talk directly to the customer.
