I make games and stuff. Let me tell you, it's pretty hard to get noticed on the internet. There comes a point where whatever you're selling will be popular enough in a closed circle that it spreads through word of mouth but before that you need to get an audience. That means some shameless advertising in social media and maybe buying some ad spaces. If you don't get that momentum whatever content you're making might be dead on arrival. A lot of people and companies making ads don't actually like annoying others with them, but it's really hard to get anyone's attention now that there's like a billion new things releasing every day.

Independent repair/handyman business pays google to place ads in their results when you search for relevant terms. In the past this was done through flyers & newspapers & billboards and such. If the business made absolutely no effort to advertise their service, then you would never be able to find them when you're looking for that service, except for through word of mouth (which is arguably a form of advertising in itself.)

Don't get me wrong, I hate ads too, and they've become far too prevalent in popular media. But they exist for a reason.

Edit: we also should have the right to block and deny ads as we wish. And at the same time, advertisers should have the right to exist. Google's recent DRM and crackdown on adblockers should be met with forceful government intervention, in an ideal world, due to their debatable monopoly over their sector.
