I've found this to be the case for myself. And "minimal" can be pretty quick - work up to a set of 5 squats with your body weight on the bar, once or twice a week, say.
I must be old or I have a different idea of minimal. A set of squats at ~200 pounds is entirely doable in time, yes, but my guess is it would be non-trivial for much of the adult population. Even when we were doing conditioning in high school I don't recall that a significant fraction of the class was breaking much over 225 or so.
Yeah I've been lifting consistently basically my whole adult life - with coaches, and squatting your body weight with proper form is difficult. Maybe 1/10 people I see regularly go to the gym actually squat at full depth. I can squat my body weight, but it took me a very long time and multiple coaches to get there with proper form.
People need to set realistic goals, like squatting _no added weight_. Seriously, squat with no bar and get your butt below your knees. That alone is a serious movement, you can get fit with just that.
