> The costs are more abstract than when paying in actual dollars

Keep in mind people are still paying in actual dollars. Companies spend money on advertisement because they want something in return, and that comes from the people being targeted from the ads. I wouldn't be surprised if the poor end up paying much more than the rich in the end. It might even be more regressive than a subscription model.

Also worth noting that their are other negative externalities as well. Health for example - the poor tend to have a much worse diet that leads to bad health conditions, and there's likely a large connection between this and the advertisements for unhealthy products.
