Even if you don't click on ads, it's not possible for you to cut them out of your sight. People see ads. They learn about the brand. If they are interested, they click on it to see more about it and if not, the brand getting registered in someone's mind is in itself a valuable asset. I believe that's the genius of Facebook, they have made the ad experience so seamless and intuitive.

Note that, people generally don't buy things the first time they see a banner about it. The process of today's digital marketing involves nurturing at multiple levels. For eg, I learned about the brand from Facebook. Then, I stumbled upon a blog post written by them. "Wow. Who are these guys? Why do I keep hearing about them?". I learned more about them and maybe bought something from them after a while. Undoubtedly, Facebook uninterrupted ads will (have?) become a major part of this funnel.
