If you are a new company starting out (suppose aluminum siding), you have to market your product or else nobody will know about it. I'm not sure what all parts of marketing are counted as advertising here, but generally in marketing you pay to get word out about your product. Wihtout that, starting a business might be tough. And then, as a consumer, there are lots of free products I have gotten my entire life by virtue of the fact that one of those companies offered to pay for it for me. If you turn that off I'm not sure how that all would work. I don't think the OP goes into too much detail.
