That was the context.
IOW, if a FF sensor array is doing the same work (capturing the same image) as a smaller sensor array, then it will be further back (lets assume same megapixels and a pin-hole camera from the same physics closet as the massless ropes and frictionless pulleys)
What you are talking about is the advantage of using existing lenses to get a larger image. ..or that you've been dragging around lenses too big for your existing sensor. That's different than saying that a larger pixel works less.

I am not even sure what your point is. You can get the the exact same image on a full frame sensor as you do on a crop sensor. You just need the appropriate (longer) focal length. The sensor would not be "further back" and the camera would be in the exact same location so the perspective would be identical.
Regardless of the lenses used, full frame sensors have technical advantages over crop sensors. The two primary advantages are low light performance and dynamic range. Both of these are directly tied to the lower density of the full frame sensor. If you are working the wide angle end of the lens spectrum, lens quality is seriously better in the full frame camp. The only real disadvantages you can associate with full frame sensors compared to crop sensors are cost and lack of reach.
