No because small businesses arent hiring ad agencies who spent years studying psychology in order to manipulate people into doing what the company wants, not what the person wants. This is very much an issue of scale

That market is made when you ban "large companies" from making ads.

Not everything has to be black and white, there is middle ground for improvement. I'm not sure anyone loves the same MegaCorp™ ad plastered all over buildings, highways and stoplights.

The size, depth, and reach of the advertising industry is a direct result of the amount of money injected into it. The current ad industry is effective, awful, anti-competitive and resembles more of a cancer at this point than it's intended purpose to provide useful information.
