I can see the case for it, I mean, I don't go into a car dealership and approve or deny which parts are to be replaced or which procedures are necessary. I have no basis for knowing.
I’m 50/50 on this. The dealerships can be mindless flow-chart followers:
It’ll say “When A occurs, try replacing X” and they’ll do that, even though my notes stated that I switched all the Xs around and the problem didn’t move with them.
Sure. And you can take steps toward dealing with ignorance that are still compatible with informed consent. For example, we should ban the advertising of prescription drugs on television. Most other respectable countries do.
Most would see that as an argument in support of paternalism, and as do I, which is why I agree with your position. Advertising drugs to consumers is akin to advertising specialty testing equipment to individuals: at best neutral and at worst harmful. You have no business self-diagnosing with a risk of stroke and running in there to demand Plavix. There should be no world in which the doctor goes, "Huh, Plavix! I've never heard of it, and if you think you're at risk of stroke, well bud, here you go, one years supply."
