At the beginning the money comes from the product owner, who without any visibility will not have (as many) costumers
If people need a product, they will find it. If they want to know about more products they might find useful, they will inform themselves — hopefully using a neutral source whose interests are aligned with theirs. Not from an advertiser which is interested in making them buy whatever garbage their customer wants to sell. Which does not educate and inform customers, enabling to make good decisions, but to manipulate them.
That money comes out of the pocket of customers. Without advertising, products would be cheaper because their producers would not have to spend money on adverts.
> Advertisement is literally as old as civilization.
So? That doesn't make it any less despicable.
