No one ever starves due to lack of advertising, advertising is not needed to let you know you need food.

And your contrived bakery example is unlikely. Ads are about letting you know a business exist, or convince you to give them another chance. Once everyone in town knows of all the bakeries, people will just pick favorites. If you’re the most famous bakery in town, you don’t need advertising. If you just started your cookie business, you do. Choose whatever advertising that works for you: signs, flyers, word of mouth, vitality stunts or just online ads. You will find that online ads are astoundingly cheap.

Again, if you serve the best croissants in town, customers will come back. (Reality is more sophisticated than that due general demand generation ideas such as just reminding you of croissants vs inferior pastries)
