Like I said, by that logic anyone who chooses not to click adverts are also stealing.
Do you click every advert you see just to make sure you're compensating for 'stolen' bandwidth, processing power, storage, electricity?
FYI: I redistribute scripts under GPL licensing. I don't ask for donations, nor do I litter my pages with advertising. I consider that pretty "giving" - and no, I don't have problems with people 'stealing' my bandwidth, processing power, storage or electricity.
No, I treat websites with the benefit of the doubt. If they provide advertising that is useful to me, I click on it.
By blocking all advertising on all websites you're sticking your fingers in your ears.
Personally, I find adverts useful. Websites that resort to crappy user experience adverts - popups/unders/flash etc usually aren't worth visiting in the first place.
You are stealing bandwidth, processing power, storage, electricity, etc
Society is about give and take. Adblocking is about take.
