Yes, but my whole point was that PCs have other uses, so Valve selling a PC at a loss can’t recover the money with games because people won’t necessarily play games on that machine. Saying “if you’re playing games” to that point is like someone explaining to you why seatbelts are needed in cars and you replying with “if you never crash they’re useless”, like OF COURSE that if we enter your hypothetical example everything works, the whole point is about the disaster that would happen if that wasn’t the case.
Re-read my answer, if they were sold at a loss like you suggested it would be beneficial for companies to purchase them to be office, servers or anything, costing Valve money without bringing them any profit afterwards because those machines would be purchased without gaming in mind, only because they were the cheapest available option (since all of the others have some profit margin and steam machines would be sold at a loss).
