The consideration I give the scout "concept" is largely scrutinization of the applicable paradigm where such a rifle is best fielded. It is hard to argue a .308win under 7lbs and under 36" with a fast reloads and a moderate to low power optic and back up irons, deployed with a detachable magazine or stripper compatibility is not highly versatile for a scenario in which the person wielding said carbine could engage limited combatant contact as well as fill a stew pot.
However - considering the era in which we live, and even such the late Colonel lived, I'm not certain I believe such a scenario really exists. I've been fortunate in my life to live in and/or travel to and hunt in many of our great United States, and I really can't say I believe there is a place where I think carrying such a rifle makes sense - legally at least. There are areas in the Southwest where risk of contact with groups of smugglers is possible while hunting, but I can't say I believe a bolt action rifle in 308win is the best option there, and it may or may not be applicable to the game you'd be after. In the remaining "frontiers" of the Great Western States, where bear encounters might be a risk while hunting, again, a .308win bolt action carbine likely isn't a great fit for either the hunt itself nor the incidental bear encounter.
It's a highly versatile platform, without question, and frankly, it is very similar in how I have laid out my few custom DGR's over the years, as it IS a versatile platform.
But if we consider Cooper, born in 1920, meaning he's a young adult in the 1940's, we're not talking about firearms fighting the frontier wilderness as they might have in the century prior. Carrying a rifle for "possibles" isn't really legal for any big game any more, save the few sustanence survival folks way up North, and for them, I could consider a Scout Rifle quite apt. But for the vast majority of Cooper followers, in what real life application is the scout rifle the BEST option at their disposal? I've lived my life with access to over 17,000 acres of hunting ground for the last ~25yrs, and have hunted western states on pack hunts on foot and on mule, and I can't say I have found the area of the US in which I think a .308win carbine is the best option.
Maybe I'm too practical in seeking application, and maybe that means the Cooper Mystique is lost on me - which I do count myself a Cooper fan and I regularly utilize his teachings in my own practice and also in my own instructing of others - but I think there's little more than mystique between an American citizen and a paradigm supporting a survivalist/lawless mentality where I might, at any moment, need to employ the same rifle as a device of hunting OR a device of human assailant defense.
Very fun rifles, very adaptable, but really not great for any given practical purpose stateside.
