It doesn't actually reinforce your point at all. Considering a single use case is looking at this from a narrow point of view. Let me be more specific, no developer is using a 4090 to create a 30 FPS experience that some gamer's don't mind. Highend GPUs like the 4090 can can be used to push resolution, ray tracing, textures, foliage, etc...to its highest* potential at a respectively frame rate beyond 60 FPS. Pushing high frame rates on consoles comes at a cost. This usually entails degraded textures, lower resolution, lack of ray tracing, reduced graphical effects, reduced foliage, and so on.
