Statins have been generic since forever, there is not much big pharma profits to be made there any longer.

It's really hard to quantify "enormous health benefits". Much of what we do has a significant placebo effect. You will see a lot of plant zealots make similar claims (I am skeptical). If you've lost significant weight that's awesome. Otherwise most people <50 are mostly healthy to begin with. Having more energy doesn't necessarily mean you live longer.

I would say if you are one of the "hyper responder" that sees your cholesterol levels skyrocket, it might be worth reconsidering the diet or re-evaluating benefits or intervention (even if that means trying more fiber). While cholesterol might turn out to be more correlation than cause of cardiovascular disease, in every other disease phenotype (familial hypercholesterolemia, etc) that shows markedly elevated cholesterol levels we see rapid progression of cardiovascular disease.
