See, that is what my initial reaction was as well. How do we know which is the chicken and which is the egg?
Like with this example:
Is an imbalanced leg causing the imbalance? (A natural compensation?)
Is the overgrown bar causing the imbalance?
Are the heels too high and causing deep collateral grooves which causes a puny frog and the hoof is flaring because of the lack of frog contact?
Are the bars robust because
the frogs aren't robust enough? Maybe they are trying to compensate for the frog?
Is it simple mechanics.....the medial side bears more of the weight of the horse, so the lateral side is being pushed outwards?
Or is it the result of years of improper trimming?
Your head can spin with all the possibilities. That is why I would love to find a magic bullet, like......."oh yeah, it's just the bars that need trimming and everything else will magically get healthier." But things probably aren't that simple.
I think there ARE correct answers to these questions, it's just we don't have enough understanding of the hoof to know the answers. But if someone scientifically studied the hoof in the example, on a live horse let's say, and tested out different theories, like trimming the bars, or lowering the lateral side, or what-have-you, they probably could find the answer(s). I just personally don't have enough experience to know first-hand what is cause and what is effect. And what we should
be trying to correct, and what we shouldn't
