Indeed true but the point also is that in reality that market would still travel to LGW/STN to fly direct to their home country if that's where the flights were available from. It might not be as convenient but people would do it. Leisure often do so already too, often willing to travel to an alternative airport for the right fare, timings etc.
The connecting hub traffic and higher yielding premium demand on the other hand depends on LHR. That's what I think the pricing structure fails to recognise. Obviously you can't dictate which airlines must fly from which airport, the market decides, but you could incentivise it with the right pricing regulations.
