You're missing a key fact, which others have noted, but I would phrase it differently.
Calcium is the end-stage of atherosclerosis. In other words, only advanced atherosclerosis has calcium. The electron beam CT test can, therefore, read zero in people with extensive atherosclerosis, if it is still in the earlier stages. As others note, even early atherosclerosis is bad.
That is why insurance doesn't cover electron beam CT -- it's a crappy test. It provides no reassurance if it's negative, and on a population scale the LDL is far more cost effective and convenient to identify people who need statins.
You might look back at studies from the early statin days, like AFCAPS/TexCAPS, which looked at healthy people like you, whose only risk factor was high cholesterol. The ones who got even the primitive statins of the day lowered their risk of a first coronary event by 37%. That doesn't even tell the whole story, because atherosclerosis can affect any artery in the body. You want your kidneys, eyes, ears, brain, legs, and penis (when present) to work well to the end of your days. Atherosclerosis is a terrible disease.
