The idea feels like sci-fi because you’re so used to it, imagining ads gone feels like asking to outlaw gravity. But humanity had been free of current forms of advertising for 99.9% of its existence. Word-of-mouth and community networks worked just fine. First-party websites and online communities would now improve on that.
The traditional argument pro-advertising—that it provides consumers with necessary information—hasn’t been valid for decades.
I have hated few things in this world as much as advertising. It is one of the few industries I feel is beyond saving and produces nothing of value at all levels. I am of the opinion that advertising is like cancer, whenever it is allowed to get a foothold somewhere it will eventually kill the host. For-profit companies can not resist the easy money promised by advertising, so the only way to combat it is not have it to begin with.
I go out of my way to pay for the things I use with money and not attention if at all possible. I will nearly always favor buying from a company that does not get most of their revenue from advertising, even if it means I pay more for the product and it is a less capable product or service.
