What does negative production mean to you here? I can run an incineration business or a demolition derby, as long as I get paid to do so. If that doesn't count

What does negative production mean to you here? I can run an incineration business or a demolition derby, as long as I get paid to do so. If that doesn't count as negative production (because I'm producing space or entertainment value; potentially at a loss to acquire market share), what does? If negative production is a physical impossibility, the claim that you can't run a business with it doesn't tell us anything about business.
