I'm afraid that what you 'think', or 'can't see', doesn't change the facts.
I would suggest you dive a bit more into the relevant litterature....
On Concorde at Mach2, roughly a quarter of the thrust came from the intakes.
And this is no theoretical speculation..... to the structural engineers it was all hard fact, because those thrust forces had to be "led" from the intake structure into the wing structure and the rest of the airframe.....
