U have some points, yes…
But keep in mind the lever arm from the hip is longer in a front squat because of the position of the bar right across the shoulders. Hence the the actual force requirements are inherently higher in the front squat(to produce the same amount of torque) compared to those in the back squat..
I think that is true only if you place the bar low on the traps (which you should) and even then the difference is probably small, maybe a few percent. Additionally, the increase in torque applied through this lever is being carried by the lower back, not the glutes and hips. If you are holding 315lbs., you can hold on your traps, your chest, or you can hold it on your head if you want, but your lower body will still be pushing 315lbs. plus your body weight, nothing more. Why make the lift more difficult if it doesn't directly impact the body parts your focusing on, in this case the glutes, hams and quads?
But all theory aside, the general consensus of just about everyone who powerlifts, including powerlifters, college football programs, etc., is that the back squat is vastly superior to the front squat in developing absolute or limit strength, so why use an inferior exercise, unless it is to hit your quads a little harder, or just change things up? Now, if you're truly going to get into an all around Oly program, and do not only the core lifts, but all the supplementary lifts that Oly lifters do, that's fine. But that takes up a lot of time, and months or years to master.
IMHO, if you're just doing a few core exercises and looking to develop limit strength that can be translated to functional strength, its tough to beat the 1-2 combo of box squats and powercleans. Of course the main criteria for any program is. "Will it motivate you to get your behind in the gym 2-4 times a week consistently, and train hard?"
