If they're operating properly there should be almost no actual metal on metal contact. "Fluid bearings" and all. It's an important aspect to how long the life of modern engines are. If you actually have metal on metal on most engine components it won't last much longer.
A CVT requires metal on metal friction to function at its most basic level. Your transmission is ultimately a war component, designed to fail.
You might as well argue the same about batteries. If you don't overly rely on DCFC, if you don't discharge them too much, if you stay in the 20-80% range mostly, if you're not constantly doing high-amperage pulls ("If you don't rag on them"), etc. Take care of it and it'll last a long time. Stress it out all the time and it'll wear out quick.
I'm not arguing batteries aren't an expensive wear component. They are, and they are largely the wear component to care about on a used one.
I'm just pointing out CVT are also an expensive wear component. It's a double standard to be OK with one while acting like the other is some odd uncommon issue. But in the end one you can usually plug in an OBD reader in and know the actual health of the battery, the other requires you trusting the owner cared and that they and you aren't just unlucky or have an extensive tear down from a mechanic.
