You're using a narrow definition of work as exchanging labor for a paycheck. I don't agree with that definition. I would define it as putting time and energy into a project to meet personal or organizational needs. One of those needs is survival, but that's not the only one. When survival needs are met, people still choose to work on a variety of things that they find meaningful or that confer social status, like artistic projects, scientific research, philosophical inquiry, creating entertainment, raising children, and building communities.
