There is an alternative model where we simply pay professional product discoverers. Think influencers, but whose customer is the fan not the sponsor. It would be a massive cultural shift, but doesn’t seem so crazy to me.
I think the fundamental difference between advertising to discoverers vs advertising to consumers is that currently “discoverers” (platforms, content creators, billboard owners, etc.) make money directly from advertisers. Success as a “discoverer” is at least somewhat correlated to income (with more money, platforms can be more successful; content creators can create more compelling content; landowners can buy more billboards). If that money is coming from advertisers, you are biasing the market to prefer discoverers that can secure the most advertiser funding, which in turn preferences advertisers that can spend the most on advertising. This isn’t fundamentally bad, since a compelling product can make a lot of money that can then be spend on advertising, but it also creates anti-consumer incentives (like marketing something that is just good enough not to return as the next best thing). On the other hand, if discoverers are paid directly by consumers, that biases the market to prefer discoverers who identify products that bring the most value to consumers for their money.
