If ads make money and money is used to build walled gardens which make more ads and money; the unregulated expansion of ads into the daily attention of ordinary people doing ordinary people things, could become a new digital serfdom for those people. Put another way, if already large companies with existing revenue streams build ad environments that essentially self-generate substantial new revenue, "economic monsters" grow themselves in legal ways without rival. Similar arguments have been made historically over other means of fiat revenue generation, but crucially those who are tasked with oversight and correction, are also benefiting from the new system, and are rationally disincentived to curb or block it. For extra zing, add "AI" to that formula as you see fit. For extra academic weight, add a few hundred pieces of evidence from the works of Thomas Piketty and Capital in the 21st Century https://en.wikipedia.org/wiki/Thomas_Piketty https://en.wikipedia.org/wiki/Thomas_Piketty
