People just don't do that. If they did, the state of things wouldn't be the way it is. It's also kinda unfair to creators whose content people consume but just don't pay for in any way, because of a variety of possible reasons (they just don't even think about it, or they don't deem them "worthy" of being paid, or it's about having to go out of their way to pay someone, and then people only paying a limited amount of "chosen" people, etc.)
