Further, how do you plan to continue consuming sunlight on your skin, without producing something to then get food and shelter to survive another day or week of absorbing sunlight? How did you buy that living time in the first place, without producing anything to get you food and shelter to be alive in the present? Someone had to produce first.
And if you want to go more elaborately into the concept economically (sunlight based energy generation), you need land and technology to turn that sunlight into consequential electricity. You must produce first to generate and consume the sun-based electricity.
