> Without advertising, it would be really difficult to run a business.
It's difficult to run a business without advertising in a world full of advertising. If others can get to your customers before they find you then yes that's a problem. But all you get from paying to advertise is to get back to where you would have been without ads (assuming your competitors spend a similar amount).
