"Lower cost to reach customers = lower product and service prices"

This is economically illiterate. Advertising is not a discount mechanism. It is a tax on the consumer. When I buy a product heavily marketed on Instagram or Google, I'm paying for the product plus the auction bid price required to acquire me plus the margin of the ad-tech middleman (which are trillion dollar companies).

You are conflating "information distribution" with "persuasive surveillance." In a world without behavioral advertising, businesses compete on quality and reputation, not on who can exploit the most psychological vulnerabilities to manufacture demand.

As for innovation: The current ad ecosystem has killed organic discovery. You can't build a "micro-business" based on merit anymore. The winner SHOULD be the engineer who solved a hard problem efficiently. But instead the winner is the dropshipper who cracked the arbitrage spread between a cheap, garbage product and a highly manipulative Facebook ad campaign.
