Everything single one of those local businesses is also doing advertising, and is probably how you found them in the first place. They're buying local newspaper adverts, using flyers, or participating in valpaks/coupon mailers.
The idea that we should eliminate that because a higher-income bracket of consumers is inconvenienced by ads just comes across oddly haughty and privelaged to me.
Heck, I wouldn't have my successful career today if it wasn't for the ad-supported ISP NetZero CD I came stumbled upon in 1999.
