If you find all advertising offensive then I think that's an issue with you, not with advertising. If you want to look at or use something that doesn't belong to you (whether that's getting on a bus, or visiting a website, or watching a TV channel) then the owners should be allowed to show you advertising if they wish. If you prefer not to see it, you can make that choice and avoid it.
Is it more desirable if it doesn't exist? Perhaps - if you really hate it all then fine, that's your opinion, but do you really hate it enough that you would prefer every website that is financed by advertising to either bill you for usage or shut down, every public transport subsidised by advertising gets more expensive, every TV channel price goes up, cinema tickets, everything...
And as to my interest being antagonistic to yours, I disagree. I (personally) want you to buy a laptop or a PC and I want you to, when you next need one of these items, consider my brand. I target audiences very tightly to try and ensure that people who see my adverts are likely to be interested, and do rather a good job of it if I say so myself. If you end up being interested in what I am advertising (as plenty of people who view them do) then great for me, great for you. If you don't, then you can ignore my adverts, I don't buy any that are overly annoying or evasive, so even without adblock installed they won't cause you any problems, you can just ignore them.
End of the day, my goal isn't to trick you into buying something you don't want, it's to make sure the people who do want to buy these things know about them, and to avoid other people as much as possible. Feel free to hate bad adverts - I do. Even feel free to hate all adverts, including mine, if you wish, though I disagree with you on this. But don't go so far as to call them offensive. They just aren't.
