Earlier quoted context omitted.
You assume advertising somehow helps the economy, but it is probably the reverse. If business A buys ads, it's competitor B is forced to do the some, or be slowly edged out of the market. Like peacock plumes, ads are mostly a tax that weighs down every business in the area.
But how can businesses may become known? I see that maybe image ads are of the peacock feather type. Informative ads, like a new movie being out in theaters, can actually be net-positive financially, at the expense of the strain on public attention.
Some argue all advertising should be banned. If that were to occur, the search burden would shift to consumers. We'd subscribe to curators like the Consumer Report or Wirecutter, storekeepers, et cetera and let them do the searching on our behalf.
This article considers something weaker. No public advertising. No billboards. Direct mail, storefront displays, in-store advertising, et cetera are still permitted.
