Honestly, though, so many ads for insurance say you don't need a doctor visit, or health checkup, or whatever. I could easily see customers getting confused thinking they wouldn't need to give over health documents because the ads are deliberately misleading.
Just because a business's practice is obvious to itself and those in the know, doesn't mean customers can get fleeced because "they should have known better". Caveat Emptor is kind of bullshit with such high information asymmetry.
