For a lot of this, I agree. That said, I make my own Scout mounts for the arms I build, and they are held in place the same way the Germans mounted their scope bases; soft solder and a close fit to the barrel. My sights don't flop about like a landed fish atop the barrel. The gun with a Scout optic of correct build (and Leupold is the only one that I know of that is making a good conventional Scout scope since Burris quit the game) is very fast to use in the field, and the Military has seen fit to adopt the technique in wholesale lots with its Picatinny rail optics used in the Sandbox.
My major reason for using a Scout scope and mount is to preserve my ability to load with a stripper clip. To me, the rifle is a using implement, not a collector's item or a work of art. I have even been known to use the (Gasp! Gag!) light dot sights. Trijicon and Aimpoint make some first class optics, and the little Optima sight has been of service in times past, and can be fitted to the original sight slide to allow use of the existing elevation works....
