There are no successful economies without blue paint, either. As far as I'm aware, there hasn't been enough testing to say much about the importance of ads.
And even if they're necessary at some level, what if the US had 90% less ads, etc.

I don't think that is true. The oldest known mass printed advertising is about 2000 years older than the oldest known blue pigment.

I think if you look at some early advertising (e.g. BCE), you'll see that most have a painfully obvious functional form of just simply announcing the existence of a product/service for the world to observe.
